JDT Compiler throws NPE in Java 1.7 [message #1033904]

I'm getting an NPE from the ECJ (version 4.2.1) compiler when running in JRE 1.7

the same project compiles properly on JRE 1.6

a CompilationProgress monitor shows that there are Total of 2493 tasks, but then I get the NPE.

any ideas?

TIA

Hi,

You should open a bug report against JDT/Core [1] with steps to reproduce.
Provide the org.eclipse.jdt.core bundle version and as many steps as possible to make sure the JDT/Core team can reproduce the problem.

Thanks,

Given the line numbers in your exception the following information would be valuable for a bug report:

What are the values of the following system properties when running on that JRE 1.7 that shows the failure:
- java.version
- java.home

I have the slight feeling some of this code was never tested on 1.7 :-/
