Description

Possibly PermGen memory leak in eval.

It loads Script class every execution of eval but never unloads and triggers "java.lang.OutOfMemoryError: PermGen space" error.

I performed GC manually by JVisualVM among the time but no effect on PermGen space (works well on Heap).

Here are the ClassLoading/Unloading trace log:

...
