Setting up network server for management tests hangs intermittently

    Affects Versions: 10.8.1.1
         Environment: Derby 10.8.1.0 - FreeBSD 8.2 (i386) - OpenJDK 6 (b20)

I've seen on three occurrences with the 10.8.1.0 and 10.8.1.1 release candidates that suites.All
has been stuck when setting up the network server decorator for the management test suite.
Here's what I see at the end of the console output (running with derby.tests.trace=true):

The exception trace is just printed to the console, but it doesn't make any test fail. (The
exception printed on FreeBSD was different, it said "DRDA_InvalidReplyTooShort.S:Invalid reply
from network server: Insufficient data." The other two looked like the one above.)

All the hangs have happened on VirtualBox instances, though with different guest operating
systems and JVMs. Probably the timing is different from what we have on physical machines.
