      Description

      When IE user sets big number to -Xmx, JVM(IE process) sometimes carshes without any information
      like dialogue or console messages in 1.4.2.

      ex.
        A java licensee specified -Xmx512m for 1GB physical memory in IE (WindowsXP(SP2,Japanese))
        IE process disapears without any logfile, message and dialogue.

      REPRODUCE :
        1) Set big number (about half of physical memory size) to -Xmx
        2) Invoke the attached test program via IE in 1.4.2
       
      NOTE :
        Behaviors of crash depends on platform, PC configuration, ...etc
        Some PC can duplicate the behavior without message, but some PC
        can not..
        
       This problem is caused from the lack of contiguous memory.
       When JVM fails to get contiguous memory, VM should show some information to user
       like 5.0 does.
