thisObject is non-null for static method in new libxposed API

[kiber-io]

I’m observing inconsistent behavior of param.thisObject when hooking static methods.

Expected behavior:
For static methods, thisObject should always be null.

Observed behavior:
On one device (older LSPosed):
thisObject = null

On another device (newer libxposed API):
thisObject = java.lang.Object@xxxxxx
thisObject.getClass() = java.lang.Object
The object appears to be an empty placeholder with no meaningful data or fields.

Questions:

1. Is this expected behavior? It seems unusual for static methods.
2. Does this behavior originate from Vector, or from the new libxposed API itself?

Additionally, I tested several of the latest debug builds from GitHub Actions, and the behavior remains the same.

Example:

XposedHelpers.findAndHookMethod(
    "com.example.Class",
    lpparam.classLoader,
    "myMethod",
    object : XC_MethodHook() {
        override fun beforeHookedMethod(param: MethodHookParam) {
            log("thisObject = " + param.thisObject);
            log("thisClass = " + param.thisObject.javaClass);
        }
    }
)

Output:

> thisObject = java.lang.Object@69cc2d6
> thisClass = class java.lang.Object

Thank you for reporting, it is my implementation error.
