ClassLoader leak with @Async, CGLIB and DefaultListableBeanFactory [SPR-11776]

[spring-projects-issues]

Colin McQueen opened SPR-11776 and commented

When redeploying a Spring application, Perm gen keeps increasing along with the classes loaded. I looked at the heap dump file using Eclipse MAT and it suspected that DefaultListableBeanFactory class was a leak.

I excluded weak/soft/phantom refs and it looks like it has to do with the @Async annotation.

This looks suspiciously like #15899, which got fixed in 3.2.7. Can you please double-check which Spring Framework 3.2.x version you have tested this against? If the problem actually remains against 3.2.8, I wonder whether the fix for #15899 was somehow lacking...

I checked again and I am using version 3.2.8.

Does anyone know a workaround?

There was a repro project provided on #15899 which shows that the original issue has been fixed. I am trying to understand what could differ in your particular scenario.

I tried to update this sample app to boot but I was unable to find any issue with it.

Would you be able to submit a minimal project that reproduce this issue with 3.2.8 or later? Thanks!

I could not find any way to reproduce the issue. Could you please provide a sample project.? If not, I am afraid there's not much we could do.
