Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server V7.0.                                *
  ****************************************************************
  * PROBLEM DESCRIPTION: A ZipException occurs on a              *
  *                      ZipFileInputStream because the          *
  *                      underlying ZipFile has been closed.     *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  ZipFileLoadStrateyImpl.getFiles() processing closes the
  ZipFile at the end of generating the files list.  But, the
  ZipFile was originally opened by the annotation scanning
  process which still had active ZipFileInputStreams using the
  ZipFile. After getFiles() closes the ZipFile, the next attempt
  to use the ZipFileInputStream results in a ZipException.
  

Problem conclusion

• EARFileImpl.getFiles() has been changed to avoid a recursive
  call to getFiles() that occurs when loading the deployment
  descriptor. This recursive call lead to the error described
  above.
  .
  The fix for this APAR is currently targeted for inclusion in
  fix pack 7.0.0.9.  Please refer to the Recommended Updates
