Hi @miklosbalazsi, I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.

Suggested Workarounds

• Bundle an older ASM (9.8.x) alongside the Java Test plugin so it coexists with the newer ASM in redhat.java. See:
  • rgrunber’s patch and test VSIX: rgrunber@ca87967
    VSIX: https://github.com/rgrunber/vscode-java-test/raw/refs/heads/fix-1759/vscode-java-test-0.43.1.vsix
• Update the com.microsoft.java.test.tp.target manifest to depend on a Jacoco version that supports the new ASM; monitor Update to ASM 9.8 jacoco/jacoco#1862 for the release.
• Reference the discussion in Gradle projects are not recognized correctly redhat-developer/vscode-java#3995 about aligning ASM versions: Gradle projects are not recognized correctly redhat-developer/vscode-java#3995 (comment)

Duplicate Issue

• Extension not loading - jacoco error #1759

I could workaroudn the problem by explicitly installed 1.46.0 redhat.java extension instead of 1.47.0

#:~/.vscode/extensions/redhat.java-1.46.0-linux-x64/server/plugins$ ls -al | grep -i asm

installing redhat 1.46.0 didnt fix the issue for me, not even downgading java-test extension it self, i even tried installing Jacoco 0.8.14 as some guy in issue comments suggested but that didnt work either, is this issue anywhere near fixed ?

edit: this worked: redhat-developer/vscode-java#4225 (comment)

VSCode is not recognizing the tests after upgrading to v1.47.0. Downgrading to 1.46.0 works again for me.

PR #1872 should resolve this class of failure.

Root cause: com.microsoft.java.test.plugin and the bundled org.jacoco.core declare a narrow org.objectweb.asm requirement, but we relied on the ASM bundle being provided by the redhat.java / JDT-LS platform. Since redhat.java's bundled ASM version varies across releases (1.46 = 9.8, 1.47 = 9.9, ...), any mismatch leaves the plugin unresolved at runtime and the test UI disappears. This is the same root cause behind #1759 and #1866.

Fix: ship the required ASM bundles (org.objectweb.asm, org.objectweb.asm.commons, org.objectweb.asm.tree) inside the extension's server/ folder and register them as contributes.javaExtensions, so the requirement is satisfied by our own bundles regardless of the ASM version the platform provides. This matches the "bundle ASM alongside the plugin so it coexists" approach suggested earlier in this thread, implemented systematically via the build allow-list.

This also decouples future Jacoco/ASM bumps from the platform's ASM version.
