[jboss-jira] [JBoss JIRA] (WFLY-9788) EJB over HTTP fails with Arrays in Request

    [ https://issues.jboss.org/browse/WFLY-9788?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13532079#comment-13532079 ] 

jaikiran pai commented on WFLY-9788:
------------------------------------

This appears to be an URL path encoding issue. Array class name representation can end up with a {{;}} semicolon in the end, which effectively means that the URL path that's built with have a unencoded semicolon, which Undertow drops off on the server side. As the result, the server side can't find the right method on the EJB to invoke on.

In short, this appears to be a bug in the wildfly-http-ejb-client library.

> I stumbled over the issue WFLY-9573. Then I updated to wildfly-http-client-1.0.9.Final which made a few invocations work. There I discovered another issue. I attached a modified Quickstart version to demonstrate it!
