Dag H. Wanvik commented on DERBY-5158:
--------------------------------------
In contrast, if we attempt to execute a query (taher than a rollback), we see
the more understandable error stack trace whose ultimate cause is given as "No
current connection":
1)
testShutdown(org.apache.derbyTesting.functionTests.tests.store.Foo)java.sql.SQLNonTransientConnectionException:
A network protocol error was encountered and the connection has been
terminated: the requested command encountered an unarchitected and
implementation-specific condition for which there was no architected message
(additional information may be available in the derby.log file on the server)
