Re: [aspectj-users] OutOfMemory error in aspectj
|
Sorry to hear you were hit by this issue - I do see it come up now and
again that the script specifies the heap size.

i agree with that.

sure
There are other -X options that are fine because they are AspectJ options...
-Xset, -Xnoinline, -Xlint
so I wouldn't police -X options in general - I would perhaps police any
that the arg parser isn't explicitly handling.
If you do me a patch, I'll look to integrate it.
cheers,
Andy.
