JDK 8 includes the PowerPC/AIX port.
The port has successfully passed all the Java SE 8 Test Compatibility Kit (TCK) tests on Fedora 19 Linux/PPC64 and AIX 7.1/PPC64. This means that our ports are fully compliant with the Java SE 8 specification on the named platforms.
Development of the port in JDK 8 is finished. We are still fixing issues of the port, but do no more downport new features. For example, the C1 compiler port will not be integrated to jdk8u.
...
AIX: The port supports AIX 5.3 and later. It is tested to be built with xlC 12. Patch level 12.01.0000.0008 or higher is required. We do not support iSeries PASE.
Linux: We build and run the VM on SLES 10.3 with gcc 4.1.2, but support it on other Linux distributions, too. The little-endian Linux variants must be built with gcc 4.8.We do not support iSeries PASE.
Processor: The port supports only 64-bit PPC machines. It recognizes Power chips 5 through 7 and generates code optimized for these processors. It lacks an instruction scheduler targeted to Power 6, which is an in-order issueing processor.
