MWAR-405 Workaround XStream incompatibility with Java9
This is a proof-of-concept implementation of a possible way to word-around
the actual incompatibility of xstreams default converters with java9.
As the maven-war-plugin does not need all of the converters (like
TreeMapConverter which is the primary cause of the issue) we can just register
only the needed ones and bypass the java9 issue
see
Caused by: java.lang.reflect.InaccessibleObjectException: Unable to
make field private final java.util.Comparator java.util.TreeMap.comparator
accessible: module java.base does not "opens java.util" to unnamed module
Happens while initializing

this PR is just a proof-of-concept, there is an email thread on the dev
list. If the idea is accepted I will submit a JIRA and official PR (some code
cleanup is needed at least)
