Do Java JVMs perform any specialization or partial evaluation type optimizations?

Question

Do any of the Java JVMs implement specialization or partial evaluation type optimizations?

Does the final keyword get used for these optimizations?

I.e., do any JVMs freeze a parameter (or exploit a parameter that has been dynamically fixed with final) and generate specialized code? — Anthony Blake

During runtime yes. In fact all known JVM flavours do it. What does a just-in-time (JIT) compiler do?

On final keyword

Do java finals help the compiler create more efficient bytecode?

Hope I got the question right.

Interesting links, but they neither one seems to directly answer the [primary] question. Of course "specialization or partial evaluation" is very vague ..
