[jboss-dev] Re: Classloading Gotcha in JDK6
Jason,
There was a bug raised on this with Sun, and it is as follows:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6434149
They are actually not going to fix this, but instead want you to use
what you describe below. We will have to change our code accordingly in
AS 5 and anywhere else for that matter to support JDK 6.

FYI,
There is an undocumented system property (besides the jvm source) in JDK
5 and 6 called "sun.lang.ClassLoader.allowArraySyntax". The default
changed from true to false in JDK6. So what this means is that in JDK6,
unless you set that property to true, if you try and load a Java array
type using a classloader (e.g. "[[B") you will get a CNFE.
The compatible solution is to either interpret array types directly (not
hard), or to use the extended form of Class.forName(), which does
understand the array syntax:
Class clazz = Class.forName(className, false, loader);
