Description

TransactonTable.java:
public ContextManager findTransactionContextByGlobalId(
....
if (entry.getGid() != null &&
entry.getGid().equals(global_id))
—
}

In the above code gid in the entry can get set to null , if the transaction the entry referes to is committed.
So second part of the above condition can get a NPE.
