[Ivan Gerasimov]

Hello all!

Would you please help review a fix for the bug?
https://bugs.openjdk.java.net/browse/JDK-6968459

It was reported that creating new InitialLdapContext() can fail with 
"javax.naming.NamingException: LDAP response read timed out, timeout 
used:30000ms", even though the specified timeout hadn't been elapsed.

The fix was provided by the filer of the bug some time ago.
Here's the webrev with this fix:

Sincerely yours,
