[jira] Commented: (WINK-193) JAX-RS 1.1 support: C004

["Mike Rheinheimer (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WINK-193?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12757999#action_12757999 ] 

Mike Rheinheimer commented on WINK-193:
---------------------------------------

To be compliant with C004, we need to know whether a given provider writer is user-defined or a system provider.  For example, if a user specifies a writer that handles Object, but we have a system writer that handles String, and the type is String, the user-defined Object writer should still be chosen over the String writer.

Since we can no longer simply rely on the order of the providers in the ProvidersRegistry as a priority list, we need some other mechanism, so you'll see a slight change to the way priority is defined and managed.

Honestly, I'm not a big fan of this mechanism, so consider this patch a suggestion for now, and committer, please review it and post your feedback/opinion.  Thanks..

The two tests that primarily drove these changes were
1)  org.apache.wink.common.internal.registry.ProvidersRegistry11Test.testGenericTypeInheritanceSorting  (from patch)
2)  org.apache.wink.server.internal.providers.entity/MessageBodyWriterProviderCorrectParametersTest.testUserProviderOverBuiltIn
