            Description

            The problem is that XStreams tries to access "comparator" field of java.util.TreeMap and this is forbidden in Java9

            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 org.apache.maven.plugins.war.util.WebappStructureSerializer

            A possibile workaround is to change the initialization of XStreams in a way that only useful converters are registers, thus bypassing the problem
