Re: [aspectj-users] OutOfMemoryError caused by ltw of Groovy?

[Andy Clement <andrew.clement@xxxxxxxxx>]

Hi,

AspectJ can weave Groovy just fine - Spring Insight uses AspectJ to
weave into Grails apps in order to collect monitoring info.

A few observations though:

1. groovy classes are *big*, bigger than their java counterparts.
When AspectJ has a problem it tries to be helpful and print out the
class containing the problem by converting the bytecode into its
'opcode' form - like you would see if you used javap.  Something has
gone wrong and in trying to tell you what has gone wrong, it has run
out of space trying to print this groovy class.  Unfortunately the
original error is lost now this out of memory has occurred.

2. From your ajcore file I notice you have an Xmx of 256m, that isn't
particularly high.

I'd recommend running with a larger Xmx, that should enable the true
error to come out as the groovy class will be printable.  Based on
that error we can decide what to do next...  There currently is a
!within(groovy) type pointcut, so you would just have to exclude them
based on their names, but perhaps lets see what the underlying error
is before doing anything else.

cheers
Andy
