Analysis

54c6748#diff-e5880682be515f702f2a448d2dbcdedf introduced the new method "configureLobs".
configureLobs uses hardcoded SQLServerConnection. But in some usecases (java-applicationserver?) the connection is not an instance of SQLServerConnection but of SQLServerConnectionPoolProxy. --> ClassCastException
