Dan Smith created GEODE-3315:
--------------------------------
Summary: NullPointerException creating a copy of a client queue
when gemfire.PREFER_SERIALIZED=true
Key: GEODE-3315
URL: https://issues.apache.org/jira/browse/GEODE-3315
Project: Geode
Issue Type: Bug
Components: client queues
Reporter: Dan Smith
In the case of an HARegion, AbstractRegionMap.initialImagePut deserializes the
value to set the haContainer. Normally, that value is a wrapped by a
VMCachedDeserializable, and deserializing it replaces it in the
VMCachedDeserializable. With -Dgemfire.PREFER_SERIALIZED=true, the value is
wrapped by a PreferBytesCachedDeserializable and deserializing it creates a
copy of the value. It doesn't replace it in the PreferBytesCachedDeserializable.
So, in this case, the haContainer is being set on a copy of the value, not the
value itself. It has no effect, and the value put into the HARegion has no
haContainer.
This is not really an issue until this member needs to provide an initial image
for another member.
At that time, a NullPointerException like this occurs:
