VM crashes with the attached test case.

Configuration :
  - WindowsXP(SP2, japanese)
  - CPU : Core 2 duo (2.4GHz)
  - Mem : 2GB
  - JDK : 6.0/5.0u11


Reproduce :

 1. Compile *.java and create .jar files (Please see make.csh)

 javac *.java
 jar -cvf base.jar A.class B.class C.class D.class E.class Base.class TestLoader.class
 jar -cvf derived.jar Derived.class TheCompiler.class Launcher.class
 del *.class

 2. Invoke the following command line.(This is described in run_one.csh)
java -client -XX:PermSize=128m -XX:MaxPermSize=128m -Xms256m -Xmx256m -XX:CompileThreshold=2 -cp base.jar TestLoader 1000 "<PATH_TO_JAR>"

ex.
 If you created derived.jar under D:\users\tbaba\test1.win\derived.jar,
 "<PATH_TO_JAR>" is "file:///D:/users/tbaba/test1.win/derived.jar".
 which is, command line will be
  d:\>java -client -XX:PermSize=128m -XX:MaxPermSize=128m -Xms256m -Xmx256m -XX:CompileThreshold=2 -cp base.jar TestLoader 1000 "file:///D:/users/tbaba/test1.win/derived.jar"


RESULT:

D:\users\tbaba\test1.win>java -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)

D:\users\tbaba\test1.win>java -client -XX:PermSize=128m -XX:MaxPermSize=
128m -Xms256m -Xmx256m -XX:CompileThreshold=2 -cp base.jar TestLoader 1000 "file
:///D:/users/tbaba/test1.win/derived.jar"
