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

    [ http://opensource.atlassian.com/projects/hibernate/browse/BVTCK-11?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=38528#action_38528 ] 

Hardy Ferentschik commented on BVTCK-11:
----------------------------------------

A possible solution discussed on the hibernate-dev irc could be to provide another Bean Validation TCK SPI. The SPI would have a method like {{getValidatorClassLoader}} which would return the class loader used to load the Validator implementation. The test would then use the this provided class loader to assert the existence of the file {{javax.validation.spi.ValidationProvider}}.
It still needs to be investigated if this actually works.

> *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()
