Andy,
Thanks for reply (somehow I did not receive email, but found it in
archive)! The patch seems to be exactly what I needed. Will be
monitoring bug status and will update when released.

1.7.2, they were kind of 'misplaced' in the move from cvs to git, but I
just found them again on my hard drive so if it works for you, >I'll try
and roll it into the next version.

Hi,
We are running our application (tomcat with number of jsps) with LTW
enabled.
-javaagent:$CATALINA_HOME/lib/aspectjweaver-1.7.1.jar
While analyzing heap dump we found that aspectj objects
(org.aspectj.*) are consuming 109M of memory. That was to the surprise
since no crosscuts were actually enabled.
<aspectj>
<weaver options="-showWeaveInfo -nowarn">
</weaver>
<aspects>
</aspects>
</aspectj>
I am fairly new to aspectj, but it looks that there is a weaving
adapter per calssloader held in memory through weak map
<Loader->World>. Each adaptor is not too bad (including referenced
objects) around 30K. But in case of jsp new class loader instance
(JasperLoader) gets created per every jsp loaded so we end up with 2K
of weaving adaptors responsible for 100M of memory in total. It looks
bad considering that aspectj is pretty much not used at all.
The overhead of 30K per jsp is quite significant in our case. Is it a
known feature or limitation of using aspectj in a web application? Is
any workaround available?
Any suggestion, thought or recommendation is very welcomed.
Thanks,
Sergei
