RFR [testbug]: 8250772: Test com/sun/jndi/ldap/NamingExceptionMessageTest.java fails intermittently with javax.naming.ServiceUnavailableException

Please, help to review NamingExceptionMessageTest test stabilization change:
There is a race condition between the closure of connection in test LDAP 
server and the JDKs LDAP client code.
Due to this race the test could generate ServiceUnavailableException 
instead of the required NamingException.

Webrev: http://cr.openjdk.java.net/~aefimov/8250772/00/index.html
JBS: https://bugs.openjdk.java.net/browse/JDK-8250772

The following modifications have been made to the test code:
a) To increase the reproduction rate of the required exception message 
the connection closure timeout has been added to the test LDAP server's  
BIND operation handler
b) ServiceUnavailableException is now treated as an acceptable exception

The modified test was successfully executed 100+ times alongside to 
other LDAP tests

With Best Regards,
