Don't install patch 16. It comes with a bug. Latest patch is patch 17. Install patch 17 (it fixes the bug of patch 16).
You can find patch on HP Support Portal if you have a valid SAID & support contract with HP.
Patch steps will vary depending upon your env (OS - Linux/ Win OS & Env- Weblogic/ Websphere or Jboss). Steps for these are mentioned in patch read-me doc. I followed the same & it worked.
