they probably mean Sun(Oracle) JVM on ARM, as far as I remember there where tons of issues with that one and in general there where tons of issues with multi threaded code during the time Java did move to the "current" memory model (was that in Java 1.5 or Java 1.6? I don't remember), through Sun(Oracle) JVM having issues on ARM was still a think after a huge part of the ecosystem moved to Java 1.6+ but I think wasn't anymore much of an issue when Java 1.8 was approaching but uh that was many years ago the my memory is a bit vague |

I wrote code or managed Java development teams from around 1996 to ~2010 and I don't remember any problems with multi threaded code or memory models. But of course you might be right if you did run Java on an ARM mobile like the Nokia.
The only challenge I remember with two high load (thousands of write transactions/sec - back then) websites were GC pauses, where we had to hire consultants to help with tuning the GCs on different machines for the high load.
