Answer 1

This is a known issue in that level of the WebSphere server in which it's unable to handle Java SE 9 modular jar packaging (it was introduced after the product shipped). There are a couple APARs for issues around that packaging, and I think you're hitting this specific one: https://www.ibm.com/support/pages/apar/PI89708

The issue should go away when you update to the latest fixpack. If that's not feasible for some reason, you'll have to manually remove all .class files from any subdirectories of META-INF in that JAXB jar.
