> If an off-heap region is also compressed and it has a problem that causes it to try to dump the contents of off-heap memory then that dump can fail with an UnsupportedOperationException. For example:
> {code}
> java.lang.UnsupportedOperationException
>         at com.gemstone.gemfire.internal.offheap.SimpleMemoryAllocatorImpl$Chunk.getRawBytes(SimpleMemoryAllocatorImpl.java:2028)
>         at com.gemstone.gemfire.internal.offheap.SimpleMemoryAllocatorImpl$MemoryBlockNode.getDataType(SimpleMemoryAllocatorImpl.java:3347)
>         at com.gemstone.gemfire.internal.offheap.SimpleMemoryAllocatorImpl$MemoryBlockNode.toString(SimpleMemoryAllocatorImpl.java:3406)
>         at memscale.OffHeapHelper.dumpOffHeapOrphans(OffHeapHelper.java:477)
> {code}
