-----------------------------------------

             Summary: intermittent test failure with 10.10 in 
tests.compatibility.VersionedNetworkServerTestSetup and 
ClientCompatibilityRunControl
                 Key: DERBY-6756
                 URL: https://issues.apache.org/jira/browse/DERBY-6756
             Project: Derby
          Issue Type: Bug
          Components: Test
    Affects Versions: 10.10.2.1
            Reporter: Myrna van Lunteren


After the workaround of DERBY-6739, it seems there is now an intermittent test 
failure happening wih the 10.10 compatibility suite.

See: 
http://download.java.net/javadesktop/derby/request_5597173
which shows failures with Linux_ia32_jdk6, Linux_jdk8-compact2, and 
Solaris_amd64_jdk6, but no others. However on this run:
http://download.java.net/javadesktop/derby/request_5597153
shows failures with Linux_amd64_jdk7, Solaris_amd64_jdk6 and 
Solaris_amd64_jdk7. 
I did not see this failure with the IBM test runs, but those run on fewer 
platforms.

There's typically 2 failures, and one error.
The error has no information.
Not every failure  has the 2nd failure.
In each case where we have the 2nd failure, it's with the combination client 
10.10.2.1 <> server 10.9.1.0) 

The stack trace for the two failures is (from: 
http://download.java.net/javadesktop/derby/request_5597153/javadb-task-3946133.html,
 Solaris_amd64_jdk7):
