[news.eclipse.tools] Null pointer exception in compiler with M4 under wi

["Brad Miller" <brad@xxxxxxxxxxxxx>]

I'm getting a null pointer exception from the compiler when trying to save
or compile newly inserted code. The code is:

public class Test {
    class CacheEntry {
        private void add(int i) {
            assert (i < 0) : "message";
        }
    }
}

If the assert is commented out, then everything is OK. This is a distilled
version of a larger program that demonstrates the problem.

The log entry is shown below:

!ENTRY org.eclipse.ui 4 4 Dec 20, 2002 09:24:15.720
!MESSAGE Save Failed
!ENTRY org.eclipse.ui 2 0 Dec 20, 2002 09:24:15.720
!MESSAGE Save Failed
!STACK 0
