### Did this work correctly in an earlier version?

No / Don't know

### Operating System

Windows 11

### JDK

Oracle JDK 22

### Apache NetBeans packaging

Apache NetBeans provided installer

### Anything else

It happened first time

### Are you willing to submit a pull request?

No

Start with the attached JfxFileContentEditorMenuController_2.zip and the reported source file, then trace the stack from com.sun.tools.javac.comp.Flow$AssignAnalyzer.visitMethodDef through org.netbeans.modules.java.source.parsing.JavacParser. Reproduce the parsing failure on the stated NetBeans 22 and JDK 22 setup; done means the source parses without the reported assertion or the failure is narrowed to a confirmed javac or NetBeans cause.
