[CentOS-devel] CentOS 6 on ppc64 - OpenJDK

the PowerPC/AIX Port of OpenJDK-7 also supports PowerPC/Linux, including
Hotspot engine [1]

We switched to the IBM JDK, which we repackaged locally based on a specfile adapted from (I think) something at JPackage.org.

For RHEL 6.x there are official IBM-JDK packages, but this JVM has, for
example, a different implementation of X509, which is incompatible with
Sun/Oracle/OpenJDK X509. As we want to have our application as portable
as possible and also want to support the hopefully upcoming CentOS-6.6
and CentOS-7 PowerPC platform, we would like to stay on OpenJDK.
