Status in openjdk-8 package in Ubuntu:

  ---Problem Description---
  Currently fdlibm optimization is disabled for PPC64, as a consequence StrictMath methods like, but not limited to, sin(), cos(), and tan() perform poorly.

  Linux vm 4.4.0-47-generic #68-Ubuntu SMP Wed Oct 26 19:38:24 UTC 2016 ppc64le ppc64le ppc64le GNU/Linux
   
  Machine Type = pKVM

  Dear maintainer, please consider applying the fix already present
  upstream. Backport is trivial. Thank you.
