Description Paul Jones 2002-12-31 16:27:02 EST

When Java compiler is set to level 1.4 (so that the new assert statements can 
be used) and an assert is used inside a nested class, an internal eclipse 
exception is thrown whenever the file is compiled.

public class Bug {
    protected class Nested {
        void foo(int i) {
            assert (i > 0);
            System.out.println(i);
        }
    }
}

Error messages:

Save Failed:null

(or)

Save could not be completed.

Reason: Errors during build

Details: java.lang.NullPointerException encountered while running 
org.eclipse.jdt.internal.core.builder.JavaBuilder.
