> Key: TAP5-2267
> URL: https://issues.apache.org/jira/browse/TAP5-2267
> Project: Tapestry 5
> Issue Type: Bug
> Components: tapestry-core

> Reporter: Dragan Sahpaski
> Priority: Minor
> Attachments: TAP5-2267.patch

>
> DefaultRequestExceptionHandler fails with ClassCastException when an instance
> of ExceptionHandlerAssistant is contributed to RequestExceptionHandler.
> This had been broken accidentally in commit
> cb3d4c853f47cccf9193c33cfd085d6ca27c8706 when implementing contributions of
> assistant classes that are autobuilt.
> Although DefaultRequestExceptionHandlerTest covers contributions of
> ExceptionHandlerAssistant instances, it didn't fail because of an oversight
> in the test.
> The patch resolves the bug (trivially) and improves existing tests in
> DefaultRequestExceptionHandlerTest which now fail without patching
> DefaultRequestExceptionHandler.
