[hibernate-issues] [Hibernate-JIRA] Commented: (BVTCK-11) Wrong usage of context classloader to discover resources in META-INF/services

[Emmanuel Bernard (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/BVTCK-11?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=38701#action_38701 ] 

Emmanuel Bernard commented on BVTCK-11:
---------------------------------------

That poses problem then because what they do goes against the spirit of the 303 spec.
The service file is a public API so are the ValidationProvider implementation and the Configuration subinterface. They are used to select a specific provider as well as use optional provider specific configurations.
I think the restricted classloader should leave these visible even in the case of the container implementation.

> *Problem Description*:
> The test uses the context classloader to discover all META-INF/services/javax.validation.spi.ValidationProvider resources and checks whether one of the resource files contains the ValidationProvider currently under the test.
> This method of checking for ValidationProvider might not work on all containers. Especially on containers with constrained classloaders (e.g. OSGi). The Bean Validation specification in section 4.4.4.1 talks about this exact problem. That's why the test should be using ValidationProviderResolver API to check for right provider instead of looking for the resource files.
> *Tests affected*: 
> org.hibernate.jsr303.tck.tests.bootstrap.ValidationProviderResolverTest#testServiceFileExists()
