RFR: 8134111: Unmarshaller unmarshalls XML element which doesn't have the expected namespace

[Aleksej Efimov]

Hi,

Please, help to review the fix for JDK-8134111 [1]. This bug was already 
resolved in standalone JAXB project and was integrated to JDK9 as part 
of JAXWS/B sync process [2].
The changes that fixed the incorrect unmarshalling behavior are located 
in StructureLoader class [3].

JDK9 change that needs review is the addition of regression test for 
this issue:
http://cr.openjdk.java.net/~aefimov/8134111/9/00/

I will be requesting approval for partially backporting the source fix 
[3] to JDK8u-dev.
Please, help to review JDK8 changes too:
http://cr.openjdk.java.net/~aefimov/8134111/8/00/

Both JDK8/9 changes were tested with JCK/JTREG tests and no failures 
were observed.

Best Regards,
Aleksej
