Exceptions returnd from remote ejb calls create ClassCastException ------------------------------------------------------------------ Key: WFLY-2717 URL: https://issues.jboss.org/browse/WFLY-2717 Project: WildFly Issue Type: Bug Components: Remoting Affects Versions: 8.0.0.CR1, 8.1.0.Final Environment: Windows, Java 1.7.0_40 Reporter: Dirk Weil Assignee: Panagiotis Sotiropoulos An exception thrown by an ejb is not marshalled correctly to the calling remote client. Instead a ClassCastException is raised. Stack trace on client: {noformat} java.lang.AssertionError: Expected: class java.lang.UnsupportedOperationException as (in)directly causing exception but: was <java.lang.ClassCastException: java.lang.Class cannot be cast to java.lang.String> Stacktrace was: java.lang.ClassCastException: java.lang.Class cannot be cast to java.lang.String at
