Applet Index deleted from Java cache when Java WebStart application is launched



      Applet Index deleted from Java cache when Java WebStart application is launched after the applets are running.

      Issue Clarification
      On 6u35 and 6u41

      RIA applet experienced runtime errors when a Java Web Start application is invoked after the applet is running.

      When the applicaion [CPSOS] is launched , it downloads multiple jar files and
      caches them in various java cache directory folders as determined by the JRE

      o C:\Users\ms\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\11\
      o C:\Users\ms\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\22\
      o C:\Users\ms\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\57\

      When a subsequent Java Web Start jnlp is invoked , it has ben observed that
      the same javaw.exe PID as the JWS application just invoked is deleting the
      IDX files associated with the application (while it is running) The
      applet then experiences runtime error messages when functionality from cached
      classes is attempted to be invoked and must eventually be closed and

      We need to understand if this is a JRE defect, or if it is something in the
      JNLP that needs to be configured differently to avoid this undesirable

      The applet does not make any direct read of the cache per the developer. e.g.
      it is not trying to predict where files are in the cache.

      ( the problem has been observed on 6u35, and 6u41 )

      The issue has been occurring with an internal JNLP based application ,
      but it can be reproduced with generic webstart apps from external site.

      The Error exception is:

      ERROR: Failed to recover corrupt cache entry, java.io.FileNotFoundException:
      index file not found ,
