Re: [abc-users] Internal compiler error while compiling AJHotDraw

Hi Guillaume,

We've now tracked this down, and the latest abc HEAD should be able to process
AJHotDraw correctly.

Note that (as discussed on this list a few days ago) there is an occurrence of
around advice with a boolean return type applying to void joinpoints; abc
marks this as an error while ajc doesn't check it since the associated
pointcuts contain a conjunct of 'if(false)'. To simplify matters, we have
added a debug flag to avoid generating (and hence checking) advice with
statically false pointcuts. Thus, you will need to add "-debug
lazyAdviceGeneration" to your command-line before AJHotDraw compiles without
errors.

Hope this helps,
- Pavel (also on behalf of Torbjörn and Julian)
