[ https://issues.jboss.org/browse/WFLY-4522?page=com.atlassian.jira.plugin.... ] David Lloyd commented on WFLY-4522: ----------------------------------- Starting in Java 9, these classes are (I believe) inaccessible hidden members of the {{java.xml.crypto}} module so I'm not sure that this solution is going to continue to work for you much longer. In addition I believe we have our own SAAJ implementation so that might be a factor. Since we're using CXF for most JAX-WS things, including providing our own API spec JAR (not the JDK's), I think you'll have to use CXF's implementation. The JDK classes will not interoperate with ours. Unfortunately I don't know much about xws-security itself, but my brief googling seemed to imply that it's mostly configuration driven. Can I ask what classes you're accessing, and what you're using them for? -- This message was sent by Atlassian JIRA (v7.5.0#75005)
