During migrating my source code base to Eclipse I got the following IntCompErr. This is on a working code which compiles fine with javac (I used IntelliJ IDEA to create the code). Not sure if any of the classes has been compiled successfully in Eclipse before the error occurred.

Do you have steps to reproduce ?
(In reply to comment #1) > Do you have steps to reproduce ? Simply created a new project, set the source folders and when the automatic build started I got the Internal Compiler Error. Unfortunately it is a commercial sw, so I cannot give you the source code...
Which build are you using?
(In reply to comment #3) M5
What happens when you rebuild your workspace? Does it happen again?
