    Description

      As reported by Enis Soztutar

      We have seen this in one of the test runs:

      We are still running with assertions on in tests, and this block is failing the assertion. Seems important:

              if (data instanceof HFileBlock) {
                ByteBuffer sliceBuf = ((HFileBlock) data).getBufferReadOnlyWithHeader();
                sliceBuf.rewind();
                assert len == sliceBuf.limit() + HFileBlock.EXTRA_SERIALIZATION_SPACE;
