browser crashes when running certain applets repeatedly

1)Install the latest hopper build
2)Replace jre\bin\jpiexp32.dll by
http://javaweb.sfbay/~jdeva/build/1.4.1/jpiexp32.dll
3)Visit http://www.real.com/games/webgames/index.html and run applets
    like Go with The Flow or Find the Difference Animal
4)Run some other applets from any web site

Note that after step 4, the browser crashes. I have attached the log file
for your reference.

Here is the stack trace of the crash:

An unexpected exception has been detected in native code outside the VM.

NOTE: We are unable to locate the function name symbol for the error
      just occurred. Please refer to release documentation for possible
