have you tried the
Java: Clean Java Language Server Workspacecommand? Can you attach a sample project?fbricon commentedon Oct 9, 2025
I could reproduce, logs show:
The latest vscode-java build embeds org.objectweb.asm 9.9.0, so https://github.com/microsoft/vscode-java-test/blob/e3eb3bd13171cd8775d5cd051907f18d6e9c366d/java-extension/com.microsoft.java.test.plugin/META-INF/MANIFEST.MF#L43 needs to be updated to relax the constraint. The previous release included 9.8.0 so it worked.
Can you please open a ticket in https://github.com/microsoft/vscode-java-test/issues?

Closing as there's nothing more we can do here. We need microsoft/vscode-java-test#1796 to be fixed and released.
