@fbricon 1.47.0 on mac , works ok. it takes thirty seconds to complete the Java build process
App CDS is automatically enabled for pre-releases. You can disable it with
"java.jdt.ls.appcds.enabled":false
and got this . config is "java.jdt.ls.vmargs": "-XX:+UseParallelGC -XX:GCTimeRatio=4 -Xmx3G -Xms1G -XX:AdaptiveSizePolicyWeight=90 -Dsun.zip.disableMemoryMapping=true", i think 3G is enoughCan you try to disable all extensions but vscode-java, and run the "Java: Clean Java Language Server Workspace" command?
@fbricon it works ok on my home windows computer (only vscode-java , all extensions same works ok ), but got this error .
Could be an orphan java process keeping a lock on some files. Normally, these processes would self-terminate after at most 30sec, if their parent PID was killed. If it keeps happening after a while, I'd say try to restart your windows session ... or computer

For me today go out "Failed to find Main Class ...eclipse\plugins/org.eclipse.equinox.launcher_1.7.100v20251111-0406.jar" from 3 days ago.
I suppose update my eclipse installation and I can't correct it I need to reinstall all.
I'm using java 21.0.10Invece di cancellare la directory org.eclipse.osgi l'ho rinominata org.eclipse.osgi.OLD ma mi da il medeismo errore.
