Java gc tests failure fix

Sometimes the GC just won't run the finalizers, so we output a warning
instead of throwing an error, so now the test-suite will pass but with a
warning if the number of objects is not as expected.

Was notably failing on RHEL6 using OpenSUSE build testing with openjdk-1.6
