[jira] [Commented] (FELIX-5563) Adding extension bundles causes
wildfy/tomcat server to fail
[ https://issues.apache.org/jira/browse/FELIX-5563?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15880449#comment-15880449 ]
Karl Pauls commented on FELIX-5563:
-----------------------------------
Well, if inside wildfly we are not loaded by a (Subclassof-)URLClassloader we can't provide extension bundle support. Right now, that is the only way we have to add an extension bundle - hence, I changed the issue type to improvement because this is asking for supporting other types of class loaders.
That said, I'm not sure what options we have in this case - I might be able to look at it at one point but meanwhile suggestions (or patches :-) are welcome.
