[Bug 1646927] Re: PPC64: Poor StrictMath performance due to non-optimized compilation
This bug was fixed in the package openjdk-8 - 8u121-b13-0ubuntu1.16.10.2
---------------
openjdk-8 (8u121-b13-0ubuntu1.16.10.2) yakkety-security; urgency=medium
* debian/buildwatch.sh: updated to stop it if no 'make' process is running,
as it probably means that the build failed - otherwise buildwatch keeps
the builder alive until it exits after the timer (3 hours by default)
expires.
* debian/rules: updated jtreg tests to use agentvm and auto concurrency.
openjdk-8 (8u121-b13-0ubuntu1.16.10.1) yakkety-security; urgency=medium
* Update to 8u121-b13, including security fixes:
- S8165344, CVE-2017-3272: A protected field can be leveraged into type
confusion.
- S8167104, CVE-2017-3289: Custom class constructor code can bypass the
required call to super.init allowing for uninitialized objects to be
created.
- S8156802, CVE-2017-3241: RMI deserialization should limit the types
deserialized to prevent attacks that could escape the sandbox.
- S8164143, CVE-2017-3260: It is possible to corrupt memory by calling
dispose() on a CMenuComponentmultiple times.
- S8168714, CVE-2016-5546: ECDSA will accept signatures that have various
extraneous bytes added to them whereas the signature is supposed to be
unique.
- S8166988, CVE-2017-3253: The PNG specification allows the [iz}Txt
sections to be 2^32-1 bytes long so these should not be uncompressed
unless the user explicitly requests it.
- S8168728, CVE-2016-5548: DSA signing exhibits a timing bias that may
leak information about k.
- S8168724, CVE-2016-5549: ECDSA signing exhibits a timing bias that may
leak information about k.
- S8161743, CVE-2017-3252: LdapLoginModule incorrectly tries to
deserialize responses from an LDAP server when an LDAP context is
expected.
- S8167223, CVE-2016-5552: Parsing of URLs can be inconsistent with how
users or external applications would interpret them leading to possible
security issues.
- S8168705, CVE-2016-5547: A value from an InputStream is read directly
into the size argument of a new byte[] without validation.
- S8164147, CVE-2017-3261: An integer overflow exists in
SocketOutputStream which can lead to memorydisclosure.
- S8151934, CVE-2017-3231: Under some circumstances URLClassLoader will
dispatch HTTP GET requests where the invoker does not have permission.
- S8165071, CVE-2016-2183: 3DES can be exploited for block collisions when
long running sessions are allowed.

Bug description:
---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.
---uname output---
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
---Steps to Reproduce---
Please refer to:
