derbynetmats/NSinSameJVM.java fails to run due to Warning 
"UnknkownHostException: dyn<xx>" on Linux with DHCP generated hostname
--------------------------------------------------------------------------------------------------------------------------------

         Key: DERBY-1432
         URL: http://issues.apache.org/jira/browse/DERBY-1432
     Project: Derby
        Type: Bug

  Components: Test  
    Versions: 10.1.2.1, 10.1.3.0    
 Environment: Linux Operating Systems using DHCP IP address *and* hostname 
generation
    Reporter: Stan Bradbury
    Priority: Minor


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
