So these are already fully offline and deterministic; nothing to change on that front. Happy to add an explicit comment in the test file noting this if it'd help future reviewers. |

Found while manually testing the reporter dialog: clicking "PasteBin" disabled the button, showed "please wait", and never resolved either way. PastebinUploadRunnable.call() makes a real HTTP POST via jpastebin with no timeout of its own, and UploadPanel.upload() just ran it on a bare thread and waited unboundedly for callable.call() to return - a slow or unreachable server left no way to tell "still working" from "will never finish". upload() now submits to an ExecutorService and waits at most 30s (configurable via a package-private constructor for tests) via future.get(timeout, SECONDS), cancelling the future and reporting a clear "Upload timed out after 30s" failure if it's not done by then. The wait-and-dispatch logic is split into a small static method, awaitUpload(), that's plain Future/Consumer plumbing with no Swing dependency - lets UploadPanelTest exercise the timeout, success, and underlying-failure-unwrapped-from-ExecutionException paths directly against real Futures, without a button-click harness. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Clicking "PasteBin" threw NoClassDefFoundError: com/fasterxml/jackson/core/type/TypeReference the first time it actually reached a Jackson class - reproduced directly by calling PastebinUploadRunnable.call() outside the dialog. jpastebin's own embedded META-INF/maven/org/jpastebin/pom.xml (inside the jar) pins jackson-databind/jackson-core/jackson-annotations 2.9.7, but the POM Gradle actually resolves for org:jpastebin:1.0.1 from the JBoss repo is an empty Nexus-generated stub with no <dependencies> at all - so Gradle never pulled Jackson in. Declares all three explicitly via the jackson-bom platform rather than three separately-pinned versions: jackson-annotations renumbered its own versioning away from core/databind's x.y.z scheme starting at 2.20, so hand-pinning all three to the same string breaks depending on which release line you pick. The BOM keeps them resolvable together regardless. 2.9.7 is a 2018 release with known CVEs; Jackson's 2.x line keeps this level of API (ObjectMapper, TypeReference, annotations) stable, so the current release is a safe drop-in rather than matching jpastebin's old pin. Verified end to end: a direct call to PastebinUploadRunnable now succeeds against the real API instead of throwing. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
uploadFailed() only ever showed a JOptionPane - nothing else in this codebase logs upload failures anywhere. That popup reaches whoever happens to be watching the screen at that exact moment and leaves no trace at all once dismissed; whoever launched the process (a script, a supervisor, a developer tailing output) has no way to find out what happened after the fact. This is exactly what made the Jackson NoClassDefFoundError above hard to pin down in the first place - it only ever appeared as a popup. e.printStackTrace(System.err) now runs unconditionally before the dialog, on the same thread, so it can't get lost even if the JOptionPane is dismissed instantly. New package-private uploadForTesting() hook (bypasses the real ActionListener/network call so UploadPanelFailureLoggingTest can drive a failure directly) plus the same GlobalProperties NPE guard used elsewhere in this repo (needed just to construct GlobalProperties() in cr-core's own test classpath - see the sibling PRs). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Addresses @BenjaminAmos's review concern on #64 (now folded into this PR): these tests are already fully offline - PastebinUploadRunnable is never instantiated, and new URL(...) only parses a string, it never opens a connection. Making that explicit in the class javadoc so it isn't mistaken for a real network-touching test again. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…n Windows `ErrorMessagePanel` never released its per-tab `RandomAccessFile` or the `WatchService`, so on Windows JUnit could not delete the `@TempDir` and all three panel tests failed with `Failed to delete temp directory`. Linux CI never noticed. The dialog now closes them via `removeNotify` on dispose. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

org jpastebin 1.0.1 PastebinPaste paste source code timeout interruption
💡 Result:
If you mean **how to create a Pastebin paste using `org:jpastebin:1.0.1`**, the class is `org.jpaste.pastebin.PastebinPaste`. Supply your Pastebin API developer key and source text, optionally set the format/title, then call `paste()`:
```java
import org.jpaste.pastebin.PastebinPaste;
PastebinPaste paste = new PastebinPaste("YOUR_API_DEVELOPER_KEY", sourceCode);
paste.setPasteTitle("Example.java");
paste.setPasteFormat("java");
String url = paste.paste().toString();
```
The library requires non-empty content and a developer key; `paste()` submits the code and returns a `PastebinLink`. ([javatips.net](https://www.javatips.net/api/jPastebin-master/src/main/java/org/jpaste/pastebin/PastebinPaste.java)) The Maven coordinates are `org:jpastebin:1.0.1`. ([mvnrepository.com](https://mvnrepository.com/artifact/org/jpastebin/1.0.1))
**Timeout/interruption:** `PastebinPaste` itself has no timeout or interruption handling. It delegates the request to `Web.getContents(...)`; the source shown doesn’t expose a timeout setting. ([javatips.net](https://www.javatips.net/api/jPastebin-master/src/main/java/org/jpaste/pastebin/PastebinPaste.java)) If you’re seeing a specific timeout or interruption exception, share the stack trace and I can help pinpoint it.

🌐 Web query:
"org.jpastebin" "Web.getContents" source
💡 Result:
`Web.getContents` is used in the **jPastebin** Java source. For example, `PastebinLink.getContents(String pasteKey)` calls:
```java
return Web.getContents("http://pastebin.com/raw.php?i=" + pasteKey);
```
The class imports `org.jpaste.utils.web.Web`; the project’s `Web.java` is listed in its source tree. ([javatips.net](https://www.javatips.net/api/jPastebin-master/src/main/java/org/jpaste/pastebin/PastebinLink.java?utm_source=openai))

Configure HTTP timeouts for the Pastebin upload.
future.cancel(true) only requests interruption. PastebinPaste.paste() uses a URLConnection without connection or read timeouts. A blocked request can continue after the timeout reports failure. A retry can then start another upload while the previous daemon thread remains active.
Configure connection and read timeouts on the upload transport, or replace it with a transport that supports timeout cancellation.

Agreed, but not in this PR: jpastebin exposes no timeout hook, so the real fix is replacing it with a direct HttpClient POST (which also removes the Jackson workaround here). Tracked as #71. This PR still strictly improves on master, where the upload hung forever with no feedback.

Accurate: cancel(true) cannot stop jpastebin's blocking socket call. Replacing jpastebin with an HttpClient POST that carries connect/read timeouts is tracked as #71 rather than expanding this PR. Holding the retry button until the socket dies would recreate the original hang.
…sts headless and Java 8 CodeRabbit and Copilot, round 1. `SwingWorker` can still deliver already-published events after `cancel()`, so a late callback could reopen a reader after `close()`; a closed flag now drops them. The failure test drove a real `JOptionPane`; tests run headless and `uploadFailed` skips the dialog there. Test used Java 10 charset overloads against a Java 8 target.

Combines #64 and #65 - both PasteBin-upload fixes found while manually testing the reporter dialog, closing both in favor of this one.
Summary
1. Upload hung forever with no feedback
PastebinUploadRunnablemakes a real HTTP call with no timeout of its own.upload()now submits to a daemon-thread executor and waits up to 30s (awaitUpload(), a plain Swing-free method so the timeout/exception-unwrapping logic is directly testable) before treating it as failed, instead of leaving the button disabled and the status label reading "please wait" forever with no way to tell "still working" from "will never finish".2.
NoClassDefFoundError: com/fasterxml/jackson/core/type/TypeReferenceReproduced directly by calling
PastebinUploadRunnable.call()outside the dialog.jpastebin's own embeddedMETA-INF/maven/org/jpastebin/pom.xml(inside the jar) pinsjackson-databind/jackson-core/jackson-annotations2.9.7, but the POM Gradle actually resolves fororg:jpastebin:1.0.1from the JBoss repo is an empty Nexus-generated stub with no<dependencies>at all - so Gradle never pulled Jackson in, and it only ever surfaced the moment someone clicked the button.Declared all three explicitly via the
jackson-bomplatform rather than three separately-pinned versions:jackson-annotationsrenumbered its own versioning away from core/databind'sx.y.zscheme starting at 2.20, so hand-pinning all three to the same version string breaks depending which release line you pick.2.9.7is a 2018 release with known CVEs; Jackson's 2.x line keeps this level of API stable, so the current release is a safe drop-in.3. Upload failures only ever showed a
JOptionPane, with no trace anywhere elseWhich is exactly what made bug #2 hard to pin down in the first place - the exception only ever appeared as a popup, gone the moment it's dismissed, with nothing printed anywhere for whoever launched the process (a script, a supervisor, a developer tailing output) to find afterward.
uploadFailed()now unconditionally prints the exception to stderr before showing the dialog - the same fix applied to the timeout case above, since both funnel through the same failure path.Test plan
UploadPanelTest- drives the timeout path directly via the injectable timeout constructor andawaitUpload().UploadPanelFailureLoggingTest- drives a forced upload failure via a package-private test hook and asserts the exception lands on stderr../gradlew build- clean.Related
