------------------------------------
Summary: Classes generated by Eval() never collected from
Permgen/Metaspace
Key: GROOVY-7646
URL: https://issues.apache.org/jira/browse/GROOVY-7646
Project: Groovy
Issue Type: Bug
Components: groovy-runtime
Affects Versions: 2.4.5
Environment: Oracle jdk8u51 and jdk8u66
Reporter: Isaac Dooley
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,
