Re: [ajdt-dev] Is feature available?

Hi Andy,

You are right, the project is an eclipse AspectJ project.

Eclipse environment setup:

Eclipse 3.3.2
AslectJ 1.5.4.200705211336
AJDT: 1.5.0.200706070619
jdk1.6.0
heap size is 1024

The project has around 8000 classes with many of them over 5000 lines of code. 
When a full build is done an out of memory occurs after some time, in the weaving process.

We don't get this problem with load time weaving...we made some optimizations in aop.xml, excluding unwanted packages, and we don't get memory problems with LT-weaving.

Regards,
Cristian.

I guess as you are using the term project, you are inside eclipse
rather than building on the command line or with Ant.  What level of
AspectJ are you on, hopefully it is at least 1.5.3 since that is when
pipeline compilation was implemented to reduce memory consumption.  I
presume you have increased the default heap size for eclipse via the
-Xmx JVM option to 512/768/1024 or something?

Eric is right that within() is the way we support this currently.  We
do have an open enhancement request to use aop.xml to control compile
time weaving.  Currently it is used in load time weaving to control,
at a high level, which packages get woven.  If the enhancement was
implemented you could control which packages made it into the weaver.
However, it isn't due to be implemented any time soon...

Really we shouldn't run out of memory building however large your
project, hence my questions about what level of compiler you are
using.
