Wrong connection object used in EmbedConnection.clearLOBMapping()
-----------------------------------------------------------------
Key: DERBY-2885
URL: https://issues.apache.org/jira/browse/DERBY-2885
Project: Derby
Issue Type: Bug
Components: JDBC, Performance
Affects Versions: 10.3.1.0, 10.3.1.1, 10.4.0.0
Reporter: Knut Anders Hatlen
Assignee: Knut Anders Hatlen
Fix For: 10.3.1.1, 10.4.0.0
I think there are two bugs in EmbedConnection.clearLOBMapping():
1) It checks if lobHashMap is non-null, but it should have checked
rootConnection.lobHashMap.
2) It calls getlobHMObj().clear() regardless of whether there is a HashMap.
This creates a HashMap object even though it's not needed, and all the
subsequent transactions on that connection have to perform cleanup on that
object.
