Key: DERBY-757
URL: http://issues.apache.org/jira/browse/DERBY-757
Project: Derby
Type: Bug
Components: Store
Versions: 10.2.0.0, 10.1.3.0, 10.1.2.2, 10.0.2.2
Reporter: Suresh Thalamati
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.
