-----------------------------------------
It should be nice to have a smaller test with less dependencies and files. Is
it possible to create patch with a unit test ?
Thanks
> ClassDescriptor ReflectionUtils ClassLoader Defect
> --------------------------------------------------
>
> Key: JCR-1858
> URL: https://issues.apache.org/jira/browse/JCR-1858
> Project: Jackrabbit
> Issue Type: Bug
> Components: jackrabbit-ocm
> Affects Versions: 1.4
> Environment: JVM 1.6.0.6/Windows XP SP2/Netbeans 6.2 Beta
> Reporter: V. W.
> Attachments: TestCase.zip
>
>
> I have stumbuled on a bug in the interaction between ClassDescriptor and
> ReflectionUtils classes:
> 1. ClassDescriptor.validateClassName() uses ReflectionUtils.forName(String)
> to resolve an annotated class by its name
> 2. ReflectionUtils is an evil stateful statics-based singleton. It has a
> field of a ClassLoader, which by default is the one that loaded the
> ReflectionUtils. The method forName(String) uses this ClassLoader to resolve
> the annotated class.
> The problem is that the ClassDescriptor assumses that the annotated class
> comes from a global ClassLoader (the one that loaded the jars), which is not
> always correct. The workaround is to manually set the ReflectionUtils
> ClassLoader field for it to use the correct ClassLoader.
> I've found this bug while working with NetBeans, writing a small Scala
> application and using ScalaTest TestNG integration for testing. Apparantly
> many ClassLoader need to by involved to run a single test.
> I've created a unit test (java only, libraries included) to reproduce the bug.
> The best solution would be for the ClassDescriptor to use a Class reference
> (the Class contains its ClassLoader reference) instead of just a class-name
> or at least pair every class-name with its ClassLoader.
