RFR: 8078057: Reapply fixes for 8073361, 8073374, 8073696

[Aleksej Efimov]

Hello,

The latest JAXWS [1] integration to JDK9 reverted back three bug fixes 
in JAXWS repository:
https://bugs.openjdk.java.net/browse/JDK-8073374
https://bugs.openjdk.java.net/browse/JDK-8073696
https://bugs.openjdk.java.net/browse/JDK-8073361

It was caused by skipped integration to upstream JAXB/WS projects. Now 
the fixes is applied to upstream projects and the proposed fix [2] 
reapplies jaxws parts of these fixes in jdk9.
JPRT testing shows no regression tests failures.

Please, review the proposed changes.

With Best Regards,
Aleksej
