    Description

      FULL PRODUCT VERSION :
      java version "1.6.0"
      Java(TM) SE Runtime Environment (build 1.6.0-b105)
      Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      Windows XP

      A DESCRIPTION OF THE PROBLEM :
      I am trying to run the following test application via Java WebStart with java 1.6 and I am getting NoClassDefFoundError exception even when row <property name="sun.lang.ClassLoader.allowArraySyntax" value="true" /> is included into JNLP file:

      public class TestApp{
      public static void main(String args[]) throws Exception{
      System.out.println(ClassLoader.getSystemClassLoader().loadClass("[Ljava.lang.Object;"));
      }
      }

      With java 1.5 this "app" does working fine.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Add property <property name="sun.lang.ClassLoader.allowArraySyntax" value="true" /> into JNLP file and run the following app:

      public class TestApp{
      public static void main(String args[]) throws Exception{
      System.out.println(ClassLoader.getSystemClassLoader().loadClass("[Ljava.lang.Object;"));
      }
      }

      There will be NoClassDefFoundError thrown.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      This app does working fine with Java WebStart with java 1.5 so I expect this app runs without errors under Java WebStart with java 1.6

      REPRODUCIBILITY :
      This bug can be reproduced always.
