Hi Mandy,

I just ran standalone JAX-WS tests and without SM results are ok, with 
SM enabled I will need some more time - our WS-harness (test framework) 
requires some permissions too so I'll need to investigate which ones are 
those. Up to now, we used single policy file which was union of 
permissions requred by WS-harness + JAX-WS runtime.

I'll ping you when have more results.
For JAX-B, we are currently unable to run standalone tests against JDK.

Thanks
Miran
