Filter out store/slots buffer entries that point into raw data objects.

Filter out store/slots buffer entries that point into raw data objects.

This is just a workaround till we found the root cause of the issue, there must be no slots for data object recorded.

One more thing, can we have a test for the byte array and string case?

[Hannes Payer (out of office), 2015-04-28 07:16:07]
