No idea if that's the case, but I wouldn't have expected Java of all things to be run under binary translation.
Why? The Java community has only just been working on ARM64 support at all over the last few years, and it's still a little limited, and macOS ARM64 support is only out a couple of weeks and only from non-Oracle third-party builders I believe.
Depends which version you have installed. It's a taken a while for the native versions to reach the mainstream channels, so unless you've specifically installed an M1 build you probably have an x86 build being run under translation.
