Spring 3.2.2 AOP has increased memory usage [SPR-10709]

[spring-projects-issues]

Kestutis Gedminas opened SPR-10709 and commented

Our project moved to spring 3.2.2 and observed increased memory usage. I tracked it down to UndeclaredThrowableStrategy. Older Spring versions used cglib implementation of it and it has memory usage fixed in
2.2.3 release.

But current spring version uses own implementation of the class which has memory issue - keeps ClassTransformer in private member when it is not actually used.
Attaching screenshots from Eclipse MAT.
In our project this uses 300-400 MB memory which gets wasted.

Thanks for the details report. We are actually using a repacked version of cglib 3.0 and it appears that, although the fix you pointed to is in HEAD, it has not yet been released in v3.X. Do you have a simple project that reproduces the issue so we can test any fix that we attempt?

I'm sorry, I don't have simple project for it.

I have pushed a potential fix for this. Would you be able to test the latest 3.2.4.BUILD-SNAPSHOT to see if it fixes your issue?
