Not able to generate JBOSS WS client code in eclispe Juno

Tried installing JBoss tools (JBoss Tools (Juno) 4.0.1.Final from eclipse market place) to eclipse juno. Set the JBOSS WS run time location by following steps.

Window->Preferences->Web Services->JBossWS Preferences->Add. Then provide a name (eg. jboss-eap-5.1.0), Home Folder should be $JBOSS_HOME (which is the jboss-as folder). JBOSS server is EAP 5.1.0.

When I right click on existing wsdl to generate client code I get below exception.

Not sure why tools is not able to find JBOSSWS runtime location.

IWAB0014E Unexpected exception occurred.

java.lang.NullPointerException
