  ****************************************************************
  When a remote managed HTTP server (IBM HTTP Server, Apache,
  etc.) the following exception may occur as the node containing
  the remote HTTP server may report back a version that is not
  compatibile with the PBKDF2WithHmacSHA1 hashing
  algorithm.
  CWWIM5107E The following nodes
  do not support the use of the PBKDF2WithHmacSHA1 hashing
  algorithm: [<<NODE_NAME>>]
  

Problem conclusion

• Updated the node version check to account for remote HTTP server
  nodes that report back a non-compatible version.
  
  The fix for this APAR is targeted for inclusion in fix pack
  8.5.5.20 and 9.0.5.7. For more information, see 'Recommended
  Updates for WebSphere Application Server':
  https://www.ibm.com/support/pages/node/715553
  

Temporary fix

• To work around this issue without the APAR installed, remove the
  remote HTTP server from the configuration, retry the failing
  operation and then re-add the remote HTTP server to the
  configuration.
