[drlvm] class unloading wastes memory

                 Key: HARMONY-5844
                 URL: https://issues.apache.org/jira/browse/HARMONY-5844
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Alexey Varlamov

Simple class unloading scenario shows that DRLVM leaks memory (and finally crashes). To reproduce,
run StressTest of lazy.test suite and watch that process gradually consumes more and more
memory. If compared to RI, the last keeps memory flat during very long runs.
Memory leaks roughly in the same rate for any execution mode, compiled or interpreted.

For convenience, there is standalone launcher org.apache.harmony.vm.test.lazyresolution.StressTest
which can vary stress load, e.g.: 
working_vm$ cd build\windows_x86_msvc_release\tests\lazy.tests\classes 
classes$ java -cp .;junit.jar -Dlazy.test.iterations=100 -Dlazy.test.threads=10 org.apache.harmony.vm.test.lazyresolution.StressTest
