5 months ago It was great if netBeans could detect and show the syntactic error. I think the switch (){ } looks a lot like a method and something goes wrong when parsing.
Well, NetBeans uses javac for parsing, and the same Unexpected tree error is shown in a notification. I'm curious that the JavacParser call at https://github.com/apache/netbeans/blob/master/java/java.source.base/src/org/netbeans/modules/java/source/parsing/JavacParser.java#L742 doesn't catch the AssertionError and wrap it in an IOException, which is possibly how to read the documentation for that method?? cc/ @lahodaj @mbien - thoughts?

What happened
A student (students are great bug hunters) when asked to create a toString for an enum inserted a switch/case instruction directly in the enum body and it did not show any syntactic error ... instead, when compiling, it just throws an exception:
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX It was great if netBeans could detect and show the syntactic error. I think the switch (){ } looks a lot like a method and something goes wrong when parsing.
Moreover, when trying to refactor/rename the file with the main class the following exception was thrown:
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX Below the messages.log file content (is there a way to submit a few files here, namely the project?)
Language / Project Type / NetBeans Component
Java with Ant
How to reproduce
1, create a project java with ant -> java application
create a class named ClassHasEnum
create an enum named EPOCH with values CLASSIC, CONTEMPORARY, NONE;
insert a switch in the enum body
Add an attribute private EPOCH epoch to class ClassHasEnum
On main method create an ClassHasEnum object: ClassHasEnum oa = new ClassHasEnum();
Menu Debug -> Debug Project (or Ctrl+F5) and the appError class appears missing
if you try shift+F11, yes it detects the syntactic error
Hope it helps improving "our" great IDE ;-) All the best, José
Did this work correctly in an earlier version?
No / Don't know
Operating System
Windows 10 and 11

JDK 21
Apache NetBeans packaging
Apache NetBeans provided installer
Anything else
Yes, everytime because is a syntactic error ;-)
