[Broker-J] Selector parsing logic error when combining NOT and LIKE

The JMSSelectorFilter.match() gives unexpected results when combining the LIKE and NOT operators.

The selector "NOT (entry LIKE '%aaa%')" and value "bbbb" returns true, as expected,

The selector "NOT entry LIKE '%aaa%'" and value "bbbb" returns false, whcih is a bug.

In both cases the method retuns true when the value is "aaaa"
