I think you’re missing that all interpreters have a compilation step that produces machine code, that’s a requirement to produce programs.
Java’s JIT compiler is the final compilation step of Java’s interpreting path running in a separate thread that turns the intermediate language to machine code. To be very clear though, the output of the standard javac compiler is not machine code that a processor understands. This is what makes Java not a compiled language. It depends on additional processes at runtime to turn the code you wrote into something a processor understands.
On the performance front, well written Java is fast enough as long as you have sufficient resources for the overhead of JVM and as long as you don’t have strict latency requirements. That makes it good for a pretty wide variety of computing tasks, but, also not a good choice for a lot of others.
I think you’re used to modern interpreted languages and are unaware of how the runtimes of interpreted languages used to work.
Something like Basic (to use a properly old example) was constantly interpreting source code during the entire run.
If I’m not mistaken Python was the first major interpreted language which by default interpreted the code into a binary format and then just ran the binary (and, if I remember it correctly, that wasn’t the case in its first version). By this point Java already JIT compilation in its VM for a while.
I think you’re committing the error of comparing modern interpreted languages with how Java worked 2 decades ago.
Very much not a thing. JIT interpreters are actually not that common. Most interpreters parse code to an AST in memory and then run execute said AST, without any compilation to machine code.
Listen to yourself the output of the compiler makes it not a compiled language. Java is a compiled language, and jvm bytecode can be compiled (see graalvm), or interpreted (and when interpreted it can be JITd)
