      Description

        Access to com.sun.jndi.ldap.pool.Pool.map isn't synchronized in several executing paths: in methods toString(), showStats() and getPooledConnection().

        In particular, this results in ConcurrentModificationException when debug information is on.

        Example of a stack trace with CME:
        Caused By: java.util.ConcurrentModificationException
