That's great feedback, thanks. Looks like it is behaving exactly as
I'd expect (phew!). Aspect compilation is rather more complex than
Java compilation, so we will use a little more memory, but of course
850M is far too much. The harder bit of work to support demotion when
compile time weaving is progressing (which would reduce typemap size),
but slowly.
cheers,
Andy
