Will java drop the bc in the future ? (e.g. 1.4 1.5 1.6) With the time by, java have a heavier bc problem.

  I believe older java versions are already incompatible with newer jvms. I couldn't find it explicitly stated but i'd be surprised if 1.4 code worked 100% correct on a 1.7 jvm. My experience so far is that the list of incompatibilities (http://www.oracle.com/technetwork/java/javase/compatibility-417013.html#jdk7 http://www.oracle.com/technetwork/java/javase/compatibility-...) between versions makes it nearly impossible to just drop code between versions. It will run, but often implementation details have changed causing significant bugs. Your mileage may vary

    I think so, the implementation is hard to control than jvms.As long as jvm can run older(e.g. 1.4) version bytecodes, jvms is compatibility, but what if jvm drop that, then support real type generic like C#, etc, that's would be wonderful.

  What is "bc"?

    I think he means "backwards compatibility".

      Thanks, I was stuck on byte code.

  If you watch talks like The Secret History and Tragic Fate of sun.misc.Unsafe ( https://www.youtube.com/watch?v=4HG0YQVy8UM https://www.youtube.com/watch?v=4HG0YQVy8UM ) you'll see that there is a move to isolate unsupported APIs and to slowly remove them once they are replaced by supported ones, but in general code that uses public APIs should continue to work without recompilation for a long time.
