Pull request overview
This PR updates the runtime interop layer to align with the newer Java.Interop value-manager shape by splitting the CoreCLR “JavaMarshal” value-manager behavior into a dedicated CoreClrJavaMarshalValueManager and extracting shared helpers, while removing superseded value-manager implementations.
Changes:
- Introduces
CoreClrJavaMarshalValueManager(reflection-backed) andJavaMarshalValueManagerHelperfor shared peer-type resolution and cast checking. - Removes the old
JavaMarshalValueManager,SimpleValueManager, andAndroidReflectionJniValueManagerimplementations and updates runtime wiring (JNIEnvInit) and project compilation items accordingly. - Adjusts trimming/DAM annotations and api-compat acceptable breakage expectations related to removed
DynamicallyAccessedMembersattributes.

Fixes CS0246: 'JavaMarshalValueManager' could not be found. The default value manager now resolves to the internal CoreClrJavaMarshalValueManager (accessible via InternalsVisibleTo), matching the pattern in JNIEnvInit. Suppress the correct trimming warnings (IL2026/IL3050) instead of IL3000. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
…alueManager CreatePeerInstance only walked the Java superclass chain, so a Java object returned through a base-interface signature (e.g. an anonymous class that implements a derived interface) was marshalled to the base interface's invoker instead of the most-derived interface proxy. When targetType is an interface, also enumerate the Java class's interfaces (recursively into super-interfaces) and select the most-derived registered .NET type assignable to targetType, mirroring the interface-walk already used by TrimmableTypeMap.GetProxyForJavaObject. Fixes JavaInterfaceLookup_BaseInterfaceReturnType_UsesDerivedInterfaceProxy, TrustManagerFactory_GetTrustManagers_ReturnsIX509TrustManager and the dependent ServerCertificateCustomValidationCallback_* tests.

… managers Extract the Class.getInterfaces() recursive walk into a shared JavaInterfaceHierarchy.FindFirst helper and use it from both CoreClrJavaMarshalValueManager.CreatePeerInstance and TrimmableTypeMap.TryMatchInterfaces, removing the duplicated JNI plumbing (getInterfaces method id + traversal) from both. No behavior change; consolidates the interface-derived-proxy resolution added in the previous commit. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
The value-manager/type-manager split reduces the IL3050 AOT-analysis warnings a basic NativeAOT app produces from 10 to 6: three distinct warnings (reflection-backed ManagedTypeManager ctor, JNIEnv.MakeArrayType, JNINativeWrapper.CreateDelegate), each surfaced twice in the MSBuild summary. Count verified from build.log of the apk and aab NativeAOT runs in CI build 1485907. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
The value-manager/type-manager split shrinks the release arm64 app: - NativeAOT: libUnnamedProject.so -10.87%, package 2,474,779 -> 2,286,363 B - CoreCLR: libassembly-store.so -7.19%, package 7,497,147 -> 7,312,827 B apkdiff flags these via --descrease-is-regression, so refresh the reference descriptions.

Mono.Android.csproj uses an explicit <Compile> item list, so the new JavaInterfaceHierarchy.cs was not compiled, causing CS0103 'JavaInterfaceHierarchy does not exist' in TrimmableTypeMap.cs and CoreClrJavaMarshalValueManager.cs. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Summary
Bumps external/Java.Interop and aligns Mono.Android's reflection-based type and value managers with the new base-class contracts. The Java.Interop bump relaxes the
[DynamicallyAccessedMembers](DAM) requirements on the virtual members ofJniRuntime.ReflectionJniTypeManager/JniRuntime.ReflectionJniValueManager, so the Mono.Android overrides no longer need to repeat those annotations and instead rely on targeted trimmer/AOT suppressions.This is a standalone slice of #11617 with no dependency on the trimmable type-map scanner/emitter or array codegen work.
Changes
external/Java.Interop→8d544738a(from70493645c).[DynamicallyAccessedMembers]annotations from the overrides inAndroidTypeManager,ManagedTypeManager, andTrimmableTypeMapTypeManager(GetInvokerTypeCore,GetTypeForSimpleReference,RegisterNativeMembers,ActivatePeer), replacing them with[UnconditionalSuppressMessage]where the trimmer still needs reassurance.JavaMarshalValueManagernow extendsJniRuntime.ReflectionJniValueManagerdirectly. It is markedsealedand carries[RequiresDynamicCode]/[RequiresUnreferencedCode], uses the baseEnsureNotDisposed ()helper, and drops its own dispose tracking andActivatePeeroverride.AndroidReflectionJniValueManagerandSimpleValueManager(and theirMono.Android.csprojentries).JNIEnvInit.CreateValueManagercreates the value manager through a local helper with the appropriate trimming/AOT suppressions for both the CoreCLR and NativeAOT paths.Tests / baselines

Carved out of #11617.
JavaMarshalRegisteredPeersextraction already merged via #11750. The trimmable managers, scanner/emitter, manifest, and R8 changes ship in their own PRs (#11749/#11751/#11753/#11769/#11794/#11796/#11798).Mono.Android compiles cleanly (0 errors).
