> It seems classes generated by Eval() are never collected, thus causing PermGen or Metaspace to fill up and the JVM to hang/crash.
> Reproduce by running the following code, after setting java option {{-XX:MaxMetaspaceSize=50m}}. 
> {code}
> 100000.times{ x -> assert 10 == Eval.x(2, 'x * 4 + 2;') }
> {code}
> After about 2700 calls to Eval the program will crash with OutOfMemoryError,
