[weld-issues] [JBoss JIRA] (WELD-894) Around-Invoke interceptors should not wrap RuntimeException into WeldException

[Marko Lukša (JIRA)]

    [ https://issues.jboss.org/browse/WELD-894?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12673605#comment-12673605 ] 

Marko Lukša commented on WELD-894:
----------------------------------

{{InterceptorImpl.intercept()}} is actually never called. Interceptor methods are called directly and both checked and unchecked exceptions are delivered to the caller unchanged (not wrapped).

Nevertheless, I changed {{InterceptorImpl.intercept()}} as requested - unchecked exceptions are now rethrown without wrapping them into WeldException. Checked exceptions are of course still wrapped, because {{Interceptor.intercept()}} does not throw any exceptions according to the CDI 1.0 spec (this is fixed in CDI 1.1).

> Currently, org.jboss.weld.bean.InterceptorImpl always throws a WeldException when the invoked method throws an exception.
> This causes all exceptions in intercepted session bean methods to be treated as system exceptions by the EJB subsystem as WeldException is a system exception.
> If RuntimeExceptions were simply rethrown, such exceptions (annotated with javax.ejb.ApplicationException) could pass through the interceptor unwrapped and be recognized as application exception in the EJB sense.
> Of course, checked application exceptions are a bigger problem that would probably require a more sofisticated solution, that could be resolved later.
