[jira] Commented: (TUSCANY-2883) [1.x] NPE occurs when doing
negative test about conformace item 60008
[ https://issues.apache.org/jira/browse/TUSCANY-2883?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12681235#action_12681235 ]
Simon Laws commented on TUSCANY-2883:
-------------------------------------
The reported error is still valid but the patch here can be ignored as the patch for TUSCANY-2884 committed all the test cases together at revision: 752817

> In ASM60008, it says that "The interfaces of the component references promoted by a composite reference MUST be the same, or if the composite reference itself declares an interface then all the component reference interfaces must be compatible with the composite reference interface. Compatible means that the component reference interface is the same or is a strict subset of the composite reference interface."
> In order to verify this statement in negative way, I wrote a composite file whose promoted component interface is incompatible with the composite reference's interface, one is CService, and the other is BService, and then a ServiceRuntimeException is expected as the result. But actually I got a NullPointerException.
