to review and comment? Attachment is the patch Thanks!
This bug is caused by wrong assumption that the GC is started
immediately to recycle un-referenced objects after System.gc() called
one or two times.
The proposed solution is to make sure the un-referenced object is
recycled by GC before checking if the reference is null.
Your patch makes its own assumptions - specifically that finalization
must eventually run. At a minimum you should add
System.runFinalization() calls after the System.gc() inside the loop.
Even that is no guarantee in a general sense, though it should work for
hotspot.
