[jira] [Updated] (DERBY-5547) NSSecurityMechanismTest fixture
testNetworkServerSecurityMechanism fails intermittentlyt
[ https://issues.apache.org/jira/browse/DERBY-5547?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Knut Anders Hatlen updated DERBY-5547:
--------------------------------------
Attachment: d5547-1a.diff
Attaching a patch (d5547-1a.diff) that makes the three tests wait for the network server used by the previous test to shut down completely before they attempt to start a new server.
Using the repro patch DERBY-4201 to expose the problem more reliably, I ran derbynet._Suite with this fix without seeing timeouts in any of these tests.
