Build failures with JDK 1.8

Using JDK 1.8, JBossWS API and SPI builds fail with javadoc errors. JBossWS-CXF build fails because of new compile requirement on interfaces availability:
( from http://www.oracle.com/technetwork/java/javase/8-compatibility-guide-2156366.html#A999387 )

Area: Tools / javac
Synopsis
Interfaces need to be present when compiling against their implementations
Description
When compiling a class against another class implementing an interface which is defined in yet another class file, such class file (where interface is defined) must be available in the class path used by javac during compilation. This is a new requirement as of JDK 8 - a failure to do so will result in a compilation error

in our it's org.jboss.spec.javax.security.jacc:jboss-jacc-api_1.5_spec artifact which is not exported by PicketBox that is causing problems.
