Resolution

The documentation has been improved containing the procedure that needs to be taken before upgrading AWI on WebSphere:

If you use WebSphere 8.5.5.x, make sure to delete the following files from the AWI folder before deploying the WAR file:

• WEB-INF/lib/jaxb-api-2.2.11.jar

• WEB-INF/lib/jaxb-core-2.2.11.jar

• WEB-INF/lib/jaxb-impl-2.2.11.jar
