-------------------------------------

             Summary: Local variable values are not discarded if closures used
                 Key: GROOVY-10918
                 URL: https://issues.apache.org/jira/browse/GROOVY-10918
             Project: Groovy
          Issue Type: Bug
    Affects Versions: 4.0.8
            Reporter: Andriy Rysin
         Attachments: TestOOM.groovy, TestOOMJ.java, groovy_oom.png

When I run the code below with 3 statements with closures inside the method the local var (parameter) values (all 4 of them) are staying in memory.
I don't see the same problem if I run corresponding Java code with lambdas.

Run TestOOM.groovy with 
-Xmx600M -XX:+HeapDumpOnOutOfMemoryError

Notice groovy fails:
Y
Z
java.lang.OutOfMemoryError: Java heap space
Dumping heap to java_pid147612.hprof ...
Heap dump file created [497819587 bytes in 0.136 secs]
Caught: java.lang.OutOfMemoryError: Java heap space
java.lang.OutOfMemoryError: Java heap space
    at test.TestOOM.test(TestOOM.groovy:31)
    at test.TestOOM.run(TestOOM.groovy:41)

But Java version does not.

It looks like all the values of s are still in memory (see screenshot), even though previous values should be discarded.
