CGLIB enhanced @Configuration classes cannot be garbage collected [SPR-8229]

[spring-projects-issues]

James Shaw opened SPR-8229 and commented

When an ApplicationContext is closed, any @Configuration class that was registered in that context does not get garbage collected. If I understand the way class loading works, this is because the ClassLoader still holds a reference to the enhanced Configuration class.

This is a problem for me because I want to create ApplicationContexts at runtime.

James,

This looks like a duplicate of #12556 which, while just recently resolved in JIRA, has actually been fixed in 3.1 snapshot builds for quite some time. Resolving as a duplicate for now, but please reopen if you continue to see the behavior after syncing up to the latest snapshots (or 3.1 M2 when it's released).
