I've finished my testing on Linux/ppc64, Linux/ppc64le, Linux/s390 and
AIX. All the tests passed successfully (with the corresponding extra
ppc/s390 patches currently under review).

I did run the tests with the following add-on to your change, which
enables AppCDS with custom class loaders on all 64-bit Linux, Solaris
and AIX platforms:

The only change required in HotSpot is in "classListParser.cpp" to
enable the feature on the named platforms. The other changes just
enable the additional tests on all 64-bit Linux, Solaris and AIX
platforms.
