> Hi,
>      As discussed on mailing-list, DirectByteBuffer uses native memory which is out of GC-control, alloc many DirectByteBuffer may cause memory-out-error if they are not GCed, even they can be GCed at that time. 
>      This happens in Harmony but not in RI. This should be a bug of Harmony.
>      Note: other native memory users, e.g., java.util.zip.Deflater, may cause this problem as well.
