> On several occasions, when running a Maven-based NetBeans Platform app from the IDE, the app fails with the exception "java.lang.ClassFormatError: Duplicate method name&signature in class file com/somepackage/project/actions/SomeClass$1". I suspect this might be related to the Compile-on-Save infrastructure. See attached log. A clean build of the entire project is then required in order to make the application runnable again.
> Previous versions of NetBeans required a clean build after changing annotations (see Bugzilla bug [221781|https://netbeans.org/bugzilla/show_bug.cgi?id=221781]). However, this new error appears even when no annotations have been changed. The specific error message shown here is also new to me--it did not appear in previous NetBeans versions.
