Fix [JBJCA-915] Activation of connector 1.5 archive doesn't happen, when ironjacamar.xml doesn't contain class-names

Could you please check the fix for JBJCA-915?

The fix will check activation in RADeployer.checkActivation() method in case of only one MCF or only one AO

The fix affects IJ only, for AS 7, I think we need the similar fix too.
