> 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
> Attachments: TestConnReuse.java
>
>
> 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.
