Currently - tag jdk9-b88, upstream: jdk9/jdk9 repo - Hotspot test
runtime/StackGuardPages is failing due to a different behavior on
ppc64le kernel mm in comparison with other architectures. When the stack
reaches the limit determined by ulimit it generates a SIG_SEGV, but with
si->si_code = SEGV_ACCERR, whilst other architectures return for same
event a si->si_code = SEGV_MAPERR.

Please, refer to https://goo.gl/w3dVsq for further details.

The following mm RFC Patch has been proposed to fix this issue:

Title:
  Openjdk8 still has failing tests on ppc64el

Status in openjdk-8 package in Ubuntu:
  New

Bug description:
  Looking at the openjdk8 buidlog for ppc64el arch on 16.04[1], there
  are a lot of failures and we want to start having these problems
  solved. These tests are also failing on upstream release.

  These are the tests that are failing at the moment:

  Since we still don't have access to open a bug on the openjdk project,
  we are tracking it on Ubuntu for a while, but the plan is to have all
  the fixes sent to OpenJDK upstream project.
