[jboss-jira] [JBoss JIRA] (WFLY-11600) org.jboss.invocation.CannotProceedException cannot be unmarshalled by the wildfly client

[Vladimir Kravchenko (Jira)]

    [ https://issues.jboss.org/browse/WFLY-11600?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13682960#comment-13682960 ] 

Vladimir Kravchenko commented on WFLY-11600:
--------------------------------------------

Sure the exception should not occur on the server, but such "internal" exceptions could happen. If it would happen, the client would not able to unmarshal it and the reason, why the request has failed is unclear for the client. The client could even think:  The client classpath is incomplete.

 Such "internal" exceptions should not be forwarded to a client as it is. One of options could be to "translate" such exceptions in a javax.ejb.EJBException preserving the exception message. 

Or introduce a kind of "Internal Server Error" exception that wraps info from the original exception in a generic form and include it in one of the "client" dependencies.

> The org.jboss.invocation.CannotProceedException either must not be propagated to a client or it must be included in one of wildfly-ejb-client-bom transient dependencies. Otherwise the client fails to unmarshal it:
