  JarFiles opened in
  org.apache.myfaces.view.facelets.util.Classpath._searchResource
  are not properly closed.  This can cause those JarFiles to
  leak,
  and in some environments that leak causes problems removing
  apps
  after shutdown.
  

Problem conclusion

• The JSF 2.0, 2.2, and 2.3 MyFaces code was updated to correctly
  close JarFiles.  For more information, please see:
