FULL PRODUCT VERSION :
java version "1.5.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta-b32c)
Java HotSpot(TM) Client VM (build 1.5.0-beta-b32c, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Gentoo Linux - Kernel 2.6.3

EXTRA RELEVANT SYSTEM CONFIGURATION :
not important

A DESCRIPTION OF THE PROBLEM :
I cannot use the JInput linux plugins with JDK1.5.0 (beta) due to the following exception:
Examining file : net/java/games/input/LinuxEnvironmentPlugin.class
Found candidate class: net/java/games/input/LinuxEnvironmentPlugin.class
Exception in thread "main" java.lang.NoClassDefFoundError: IllegalName: net/java/games/input/LinuxEnvironmentPlugin
   at java.lang.ClassLoader.preDefineClass(ClassLoader.java:459)
 
With 1.4.2.03 and same classpath, file layout whatever it works without problems.

I reported this problem here http://www.javagaming.org/cgi-bin/JGNetForums/YaBB.cgi?board=jinput;action=display;num=1064924636


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Install JInput & JUtils (from javagaming.org)
2. Install linux controller plugin for jinput (~/controller/* or .../lib/controller/*)
3. Invoke ControllerEnvironment.getDefaultEnvironment().getControllers();


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Class LinuxEnvironmentPlugin should be loaded successfully.
ACTUAL -
 java.lang.NoClassDefFoundError is thrown.

Last two lines are user code:  JInputTester.java:25 is
controllers = ControllerEnvironment.getDefaultEnvironment().getControllers();

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
// JInput & JUtils should have been installed => accessible via classpath
// Linux-Plugin files should have been copied to ~/controller or .../jre/lib/controller

import net.java.games.input.*;

public class JInputBug{
public static void main(String... args){
            controllers = ControllerEnvironment.getDefaultEnvironment().getControllers();

             for(Controller c : controllers){
                 System.out.printf("controller found: %s\n", c.getName());
              }
}
}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
No workaround available.

Release Regression From : 1.4.2_03
