GenericSOAPHandler import in the AbstractPicketLinkTrustHandler breaks PL 2.1.6 compilation for EAP 6.1. But it is only used in Javadoc.

Originally reported by Lin Gao (jboss-as maillist):

I am upgrading picketlink-federation to 2.1.6.Final for EAP 6.1.0.

It requires 'org.jboss.wsf.common.handler.GenericSOAPHandler' to
compile[1], which belongs to jbossws-common:1.4.1.GA, but we have
updated jbossws-common to version 2.1.1.Final, in which the package
'org.jboss.wsf.common.handler' is missing. After consulted with Jim Ma,
I know this package has been moved to jbossws-api, and renamed to
'org.jboss.ws.api.handler'. So I plan to make a patch to use the new one
during the EAP building.
