Creating a Plugin-Project is no problem. The error only occurs under Mac OS X or Linux. In Windows XP it works fine.

This stacktrace can only happen when selectedCompliance= JavaCore.getOption(JavaCore.COMPILER_COMPLIANCE); returns null. This should never happen and would be a problem in JDT/Core. I just tried on the Mac with 3.3.2 that creating a Java projects works. Maybe this has to do which JRE's are found. Could it be that the JRE detecter succeeds to write 'null' to JavaCore.COMPILER_COMPLIANCE ? Or did you import preferences before you did this? What does the 'Java > Compiler' preference show as configured compliance?
According to the Jazz bug, Kim Herzig cannot reproduce this bug any longer. Looking at the code, I don't see how this can happen. Marking as WORKSFORME.
Verified for 3.4M6.
