No - I meant pointcuts on their own are free - there is no cost until you attach advice.  So you don't have to eliminate any pointcuts you aren't using yet in order to try and reduce memory consumption.

>From the body of the method it has included in your trace, there certainly are a few advised join points aren't there.

However, it still looks a bit like it is crashing whilst crashing - can you reduce it further?  I'm expecting to see an error that is nothing to do with memory.

The best way forward for you might to weave whatever it is in pieces rather than all in one go.  Can you do some subset of the classes then another bunch of them?  I imagine there are interdependencies but as long as the types are accessible on the classpath, they will be found.

Andy.

Hi Andy,

Thanks for the response. This is a similar error, but in the weaver code (with half the join points and advice). I hope this helps a bit more.

Also from what you are saying, does it mean that I am less likely to run over the limits if I implement my aspect like this

pointcut p1() : x

pointcut p2(): y

after(): p1() || p2() {
z
}

instead of

pointcut p1(): x

after (): p1() {
z
}

pointcut p2():y

after(): p2() {
z
}

TIA,
-S-
