The PowerPC/AIX port supports JDK 7, but this port will not be . This port was not integrated into the OpenJDK main line for a long time, but finally was integrated into the codeline for extended support maintained by RedHat.  It will remain We will continue to do critical fixes in the repository of the PowerPC/AIX port (ppc-aix-port/jdk7u).  We will update this repository with update releases of the OpenJDK 7 and integrate all fixes we do in the PowerPC/Linux and PowerPC/AIX code base.

The port has successfully passed all the Java SE 7 Test Compatibility Kit (TCK) tests on SLES 11.1 Linux/PPC64 and AIX 5.3/PPC64.

The JDK 7 port supports the following parts of the OpenJDK: 

Supported operating systems and processor implementations

...

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 variant must be built with gcc 4.8. . SAP does not do continuous tests for the little-endian variant.

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. 

Status (see also the main page of the port):

As of December 2018 SAP will no more actively support jdk7u/jdk7u.

In 2016 the ppc-aix-port/jdk7u has been integrated into the main jdk7u code line.
