RFR[testbug]: 8251189: com/sun/jndi/ldap/LdapDnsProviderTest.java failed due to timeout

[Aleks Efimov]

Hi,

LdapDnsProviderTest was seen failing due to the timeout caused by the 
blocked bind operation. That could happen if there is a local process 
listening on the port specified in the test URL.
To make LdapProviderTest.ProviderTest.call fail the LDAP connect timeout 
property needs to be set to greater than 0 value. That will help 
runLocalHostTestWithRandomPort to fail with the timeout exception if the 
port is busy and try another random port.
Also, the test output has been modified not to print stack traces for 
the expected exceptions.

JBS: https://bugs.openjdk.java.net/browse/JDK-8251189

The test was executed 100+ times alongside to other LDAP tests and was 
not seen failing with the
  proposed changes.

With Best Regards,
Aleksei
