  52  * The LDAP context implementation.
  53  *
  54  * Implementation is not thread-safe. Caller must sync as per JNDI spec.
  55  * Members that are used directly or indirectly by internal worker threads
  56  * (Connection, EventQueue, NamingEventNotifier) must be thread-safe.
  57  * Connection - calls LdapClient.processUnsolicited(), which in turn calls
  58  *   LdapCtx.convertControls() and LdapCtx.fireUnsolicited().
  59  *   convertControls() - no sync; reads envprops and 'this'
  60  *   fireUnsolicited() - sync on eventSupport for all references to 'unsolicited'
  61  *      (even those in other methods);  don't sync on LdapCtx in case caller
  62  *      is already sync'ing on it - this would prevent Unsol events from firing
  63  *      and the Connection thread to block (thus preventing any other data
  64  *      from being read from the connection)
  65  *      References to 'eventSupport' need not be sync'ed because these
  66  *      methods can only be called after eventSupport has been set first
