Would love to help, but I can't either. I have IBM Power 550 Express hardware but only few resources are available to build a reliable developer software infrastructure for testing Lucene/Elasticsearch on non-x86 hardware. IBM JVM is a black box with an unknown state of open/fixed errors, making the whole developer process indeterminable and fully dependent on IBM. I think this vendor lock-in shows how much worth it is to be dedicated to open source like the OpenJDK is.
