This is to temporarily enable a currently-disabled(but will be enabled in JDK8) compiler feature.

Hmm, perhaps I missed some step. I believe I did 'rm -fr build' for each attempt to make build. Perhaps I forgot to clean up some environment variable.

Anyway, I am looking for a way to add that flag for now so we don't have to be blocked on integrating the feature. Ideally in a limited scope just to minimize the impact. If not possible, what's the suggested way to change it?

BTW, I tried OTHER_JAVACFLAGS with configure, same error for javadoc. So I assume there is a separate flag to be set for javadoc's purpose?

Cheers,
Henry
