[groovy-dev] OOM because ScriptEnginge Memory caches all ever compiled Groovy Classes

Hello,

im using Groovy in a Java Applikation through ScriptEngineManager.
Im calling Groovy scripts every few seconds and im experiencing a
Memory Leak in my applikation.

To demostrate you can use this examples:

With Memory Leak:

public class GroovyLauncherWithLeak {
       public static void main(String[] args) throws InterruptedException,
ScriptException {
               ScriptEngineManager manager = new ScriptEngineManager();
               engine = manager.getEngineByName("groovy");
               int counter;
               while (true) {
                       StringBuilder sb = new StringBuilder();
                       sb.append("return \"hello
").append(counter).append(" \"");
                       long start = System.currentTimeMillis();
                       engine.eval(sb.toString()9;
                       System.out.println("Duration: " +
(System.currentTimeMillis() -
start) + "ms" );
                       Thread.sleep(50L);
                       counter += 1;
               }
       }
}
