Subject [jira] Commented: (DERBY-1432) derbynetmats/NSinSameJVM.java fails to run due to Warning "UnknkownHostException: dyn<xx>" on Linux with DHCP generated hostname

    [ http://issues.apache.org/jira/browse/DERBY-1432?page=comments#action_12426451 ] 
            
Andrew McIntyre commented on DERBY-1432:
----------------------------------------

Hi Ole, check the derby.logs for these failures on your machines. They will contain a "Warning:
UnknkownHostException: dyn<someIP>: dyn<someIP>." if this is the same failure
as DERBY-952.

>             Project: Derby
>          Issue Type: Bug
>          Components: Regression Test Failure, Test
>    Affects Versions: 10.1.2.1, 10.1.3.0

> The test derbynetmats/NSinSameJVM.java reports that the Network Server failed to start
and aborts on Linux machines that use DHCP to generate a hostname that reflects the generated
IP address (e.g. hostname like: dyn<xx> where <xx> is the IP address string like
216101116144).  Network server does, in fact, start.
> derby.log entry:
> Warning: UnknkownHostException: dyn<someIP>: dyn<someIP>.
> Server is ready to accept connections on port <some-port>.
> derbyall.sum entry:
> > FAIL Network Server did not start
> Test Failed.
> *** End:   NSinSameJVM jdk1.5.0_07 DerbyNetClient derbynetmats:derbynetmats 2006
> Appears to be related to reported JVM issue: Bug ID:   	 4665037
