I don’t disagree, but I was responding to a claim that the JVM has _all_ the advantages of fully native languages. Fully native allows you to choose to have no runtime, or a garbage collector, and in some environments (realtime, OS kernel, AAA games) that is overwhelmingly the preferred option.

Are you quite sure of that? I think you're getting stuff mixed up here. AFAICS, a native-compiled language might very well have mandatory garbage collection. Not that any such language immediately springs to mind, and I'm not even sure any do actually exist, but surely they could exist. The concepts "native compilation" and "garbage collection" are, AIUI, orthogonal.

There were/are a bunch of Java to native compilers.

in Java you can turn off the GC completely

and you can also compile to native code

You can in theory turn off gc but in practice no one does this because nearly everything is written with the assumption that allocations will be cleaned up by the gc. The compiler has no switches to help you run in a non-gc’d state. At best you can control when you run the gc.

zero garbage Java it is relatively common in algorithmic trading

that's funny, I could swear we do
