Subject: [PATCH] Update the LDAP request handler to provide a mechanism that attempts to detect whether the JVM is susceptible to the issue described in CR 6322825 in which calls to the NIO select() method fail. If this problem is detected, a detailed error message will be written to the log and the LDAP connection handler will not be started.
