[9] RFR: JDK-8054548: JAX-WS tools need to updated to work with modular image

[Miroslav Kos]

Hello,
please review following change:
JBS: https://bugs.openjdk.java.net/browse/JDK-8054548
webrev: http://cr.openjdk.java.net/~mkos/8054548/jaxws.00/

It is basically replacing obsolete code using core reflection by 
javax.tools API plus removing old unused code.

I ran the unit tests against both standalone JAX-WS and jdk, no 
regressions occurred.

Thanks
Miran
