Fabric8 InvocationTest hangs on HPUX

This test hangs on HPUX. The test currently hangs here: https://github.com/jboss-fuse/fabric8/blob/1.2.0.redhat-6-2-x-patch/fabric/fabric-dosgi/src/test/java/io/fabric8/dosgi/InvocationTest.java#L286 (see below) although the first time I ran it I'm fairly certain it was hanging here: https://github.com/jboss-fuse/fabric8/blob/1.2.0.redhat-6-2-x-patch/fabric/fabric-dosgi/src/test/java/io/fabric8/dosgi/InvocationTest.java#L383

I will add timeouts to the test so it no longer blocks the build from completing.
