The javax\xml\ws\8046817\GenerateEnumSchema.java fails on latest JDK9 builds. Most probably the failure is related to the changes introduced by JDK-8060056 , JDK-8059977.
It looks like that schemagen (com.sun.tools.internal.jxc.SchemaGenerator) tool source code needs to be examined and modified to address these changes.
