PM19307: SIP APPLICATION DEPLOYED AS AN OSGI BUNDLE FAILS WITH CLASSCASTEXCEPTION

APAR status

• Closed as program error.

Error description

• The OSGi Applications feature pack has a servlet filter that
  prevents resources in the OSGI-INF and OSGI-OPT directories to
  be displayed out of a Web application bundle (WAB). This
  filter was written with the assumption that all servlet
  requests coming into a WAB are HTTP requests.
  
  This assumption results in a ClassCastException out of
  OsgiDirectoryProtectionFilter#doFilter when the request is not
  a HTTP request.
  
  Customer found this problem in the special case of SIP requests
  coming into a WAB.

  The OSGi Servlet filter incorrectly assumed that all servlet
  request was a HTTP request. In this scenerio it was a SIP
  request. The exception seen is:
