ASSERT FAILED calling setTransactionIsolation checking isolation_ == level   on  pooled connection
--------------------------------------------------------------------------------------------------

                 Key: DERBY-4343
                 URL: https://issues.apache.org/jira/browse/DERBY-4343
             Project: Derby
          Issue Type: Bug
          Components: JDBC, Network Client
    Affects Versions: 10.6.0.0
            Reporter: Kathey Marsden


For DERBY-4314, I thought I would do a little testing to understand the server round trips
in various scenarios for pooled connections.  So I wrote the small attached program ConnReuse.java
and hit this assertion in client:


Exception in thread "main" org.apache.derby.shared.common.sanity.AssertFailure: ASSERT FAILED
        at org.apache.derby.shared.common.sanity.SanityManager.ASSERT(SanityManager.java:98)
        at org.apache.derby.client.am.Connection.setTransactionIsolationX(Connection.java:987)
        at org.apache.derby.client.am.Connection.setTransactionIsolation(Connection.java:915)
        at org.apache.derby.client.am.LogicalConnection.setTransactionIsolation(LogicalConnection.java:253)
        at TestConnReuse.main(TestConnReuse.java:32)
---------------

To run the program on trunk:
java org.apache.derby.drda.NetworkServerControl start
java TestConnReuse.

This needs more investigation, but I thought I would go ahead and log the bug.  I tried this
only on  trunk.  I  have not yet
- Tried it on the branches.
- Tried it with Lily's DERBY-4314 patch.
- Tried it with embedded.
- Tried actually doing something with the prior logical connection which might be related.
