[jboss-dev-forums] [Design the new POJO MicroContainer] - JBREFLECT-50, determining need for setAccessible bug

[scott.stark@jboss.org]

I ran into a curious behavior I either never knew, or forgot regarding access permissions via reflection. In order for a method to be accessible via reflection without calling setAccessible on the method, both the method and the class have to be public. A public method in a non-public class cannot be accessed by the resulting java.lang.reflect.Method object. It fails with an java.lang.IllegalAccessException like that shown on JBREFLECT-50. I also show the required change to allow the ReflectMethodInfoImpl to determine when a call to setAccessible is needed.

I'm going to need a new jboss-reflect release for the current work I'm doing on JBAS-6285. Its the jdk platform mbeans that are instances of non-public classes implementing a public interface that I cannot create valid ManagedObjects for because of this issue. Can I do a 2.0.3.GA release to pickup this fix for inclusion into jbossas 5.1.x?
