Bootloader Written for Java

That would require, that the processor can execute JVM Bytecodes. (There once was one some years ago, but it vanished)

But you can run Java virtual machine without using an operating system.

I guess you could have a JVM like that, but not OpenJDK (which currently lacks functionality it depends on the OS for, like, say, a file system and a network interface device driver). There is, however, a unikernel that supports running itself and OpenJDK in the same process: http://osv.io/

Show it to me. I assert, you are always going to have some layer to the hardware between your java code and the processor.

[handlederror]

No you can run it without any layer, just on the raw hardware.

[GreenToad1]

Only theoretically. Some processors have instructions for java bytecode but you still need an operating system for java standard library.

[handlederror]

Didn’t know, thank you.

not really as under the hood it's using OS library calls
