Hi David, Many thanks for the comments. In relation to the ARMV5 support, in the past Oracle released a version for Mindstorms: http://www.oracle.com/technetwork/java/embedded/downloads/javase/javaseemeddedev3-1982511.html but if you observe that release was Java 8. For Java 9, we could

I believe the problem is that the VM is now using more atomic load/store of java longs and we don’t support these operations on multi-processing ARMv5 systems due to the lack of low level atomic instructions. On non MP ARMv5 systems, we use load/store multiple instructions. If you can
