It can wait for a future pull request, but I think the LoadCommand class hierarchy ought to be constructed from the input rather than via a call to readCommand(). That will allow many of the fields of those classes to be final.

getBytesAt(nameAddress, stringBuffer);

If you use StandardCharsets.ASCII you wan't have to catch UnsupportedEncodingException.

DDR: add support for OSX core files
6ef4f50 
Added a core reader for reading OSX Mach-O core files.
Parts of the core reader remain unimplemented, however enough is done
so that DDR can be used on the OSX core files.

ibmruntimes/openj9-openjdk-jdk8#278 seems to have fixed jdmpview, but the two testDDRExt_* tests must not be using jdmpview and will need to be fixed separately.
