What limitations does the JVM impose on tail-call optimization
Clojure does not perform tail call optimization on its own: when you have a tail recursive function and you want to have it optimized, you have to use the special form recur. Similarly, if you have two mutually recursive functions, you can optimize them only by using trampoline.
Does current JIT optimize generated machine codes for branch prediction based on runtime statistics?
Some JVMs would compile Java byte code into native machine code. We know that there are lots of optimizations we could apply for that. Recently, I also learn that a branch operation may block the CPU and affect the performance significantly, if a CPU makes a wrong prediction.

How are Scala Traits implemented in the JVM?
I have been reading about traits in Scala. They are pretty amazing. I am curious how they extend a class without actually resulting in multiple inheritance. I know that the JVM doesn’t support multiple inheritance, so I am wondering how these extensions work. Is the language just providing syntactic sugar for composition? Or is the code within a trait duplicated in each class that uses it?

What makes JVM so much versatile to support so many JVM languages?
JVM supports so many languages other than Java like Groovy,Clojure,Scala etc which are functional languages unlike Java(I am referring to Java before Version 8 where Lambda's are not supported) that doesn’t support functional capabilities.On a high level what makes the JVM so versatile that it can support both Object Oriented as well as Functional languages?

Java Compiler and VM Compatibility
A co-worker and I recently had a discussion about Java versions and the JVM. I use Java 7 but we use Java 6 for our client (while he says that some are still on 5). My immediate thought was, why can’t we target those VMs too?
