### Apache NetBeans version Apache NetBeans 27 latest release candidate ### What happened A smoke test which I run during each release which opens all ~800 NB modules and lets NB index them found a potential classloader leak. Metaspace grows during indexing, closing projects or GC does not free it afterwards. looks like this once all projects indexed: <img width="1045" height="559" alt="Image" src="https://github.com/user-attachments/assets/f03bed8d-a855-4498-82bb-fa72767542a6"; /> setting `-J-Djava.source.aptutils.disable.classloader.cache=true` does seem to help and GC appears to free resources again, but this might be only part of the story. <img width="1342" height="585" alt="Image" src="https://github.com/user-attachments/assets/43f3087e-e0ff-4fe9-ab30-7219682ede2c"; /> ### Language / Project Type / NetBeans Component _No response_ ### How to reproduce ```bash set -e # opens all netbeans modules as code scanner smoke test # 1) build netbeans and change netbeans project JDK to "default" # 2) run script in netbeans project NB="/path/to/extracted/zip" JDK="/home/mbien/dev/java/jdk-25-ea_b32" OPEN=$(find -maxdepth 2 -mindepth 2 -type d\ -not -path "./.git*"\ -not -path "./nbbuild/*"\ -not -path "./dist/*"\ -not -path "./ide/xml.core"\ -not -path "./nbi/*" | sort | xargs) #-J-Djava.source.aptutils.disable.classloader.cache=true FLAGS="-J-Dorg.netbeans.modules.parsing.impl.indexing.LogContext\$EventType.PATH.treshold=20" "$NB/bin/netbeans" --userdir /tmp/nbusr$$ --jdkhome $JDK $FLAGS $OPEN ``` ### Did this work correctly in an earlier version? No / Don't know ### Operating System linux ### JDK 25 ### Apache NetBeans packaging Apache NetBeans binary zip ### Anything else _No response_ ### Are you willing to submit a pull request?
