Java JIT compiler for download

Question

I want to download a JIT compiler for Java. Where can I get a good JIT compiler?

Answer 1

The JIT compiler runs as part as the JVM - it's not something you download and run separately.

In the early days of Java, you used to be able to run a JIT as a plugin - but these days there's no need. Any mainstream, modern desktop Java environment will include a JIT.
