### Apache NetBeans version Apache NetBeans 24 ### What happened New install on gentoo from https://cgit.gentoo.org/dev/fordfrog.git (portage overlay), every opened project doesn't support code completion. Tried(as suggested on netbeans boot) with openjdk23 but ide doesn't recognize that is has bean lunched with it (warning still occurs), nb-javac doesn't downloading. ### Language / Project Type / NetBeans Component java, maven, spring ### How to reproduce Create new project then new class - done, code completion not working ### Did this work correctly in an earlier version? No / Don't know ### Operating System Gentoo(kernel 6.6.62-gentoo-x86_64) ### JDK 17, 23 ### Apache NetBeans packaging Other ### Anything else in logs i see: ``` NFO [org.netbeans.modules.parsing.impl.SourceCache]: Parser factory: org.netbeans.modules.java.source.parsing.JavacParserFactory@792287cf returned null parser for Snapshot 944010107: CashCardJsonTest.java INFO [org.netbeans.modules.parsing.impl.SourceCache]: Parser factory: org.netbeans.modules.java.source.parsing.JavacParserFactory@792287cf returned null parser for Snapshot 1005017317: CashCardApplicationTests.java WARNING [org.openide.filesystems.Ordering]: Not all children in UI/ToolActions/ marked with the position attribute: [Files, Java, org-netbeans-modules-gsf-testrunner-ui-TestCreatorAction.shadow], but some are: [io-github-moacirrf-javadecompiler-DecompileAction.shadow] INFO [org.netbeans.modules.parsing.impl.SourceCache]: Parser factory: org.netbeans.modules.java.source.parsing.JavacParserFactory@792287cf returned null parser for Snapshot 543755576: CashCardApplication.java INFO [org.netbeans.ui.indexing]: Indexing finished, indexing took 493 ms.
