[jboss-jira] [JBoss JIRA] (WFLY-12827) Class not found com.sun.xml.internal.ws.encoding.StringDataContentHandler

[Dominik Derwiński (Jira)]

    [ https://issues.jboss.org/browse/WFLY-12827?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13818491#comment-13818491 ] 

Dominik Derwiński commented on WFLY-12827:
------------------------------------------

I think this can be closed, WildFly has proper jars for JavaMail. When using them MailcapCommandMap is properly initialized, because the mailcap files and extra classes exist on classpath, unlike when JAXB or JAX-WS reference implementations pull wrong (new, but stripped) activation library.

> Maybe it's just missing module dependency for javax.mail.api, maybe you need to include JAXB and JAXWS libraries in WildFly modules for use on JDK 11+, when they were removed from JDK.
