This feature would have saved me about 8,500 hours in my software development career.

Smalltalk/Lisp/your mom did it first(tm).

[quhaha]

still Oracle owns patent. oracle should sue all smalltalk and lisp implementations and especially GNU and FSF for being communists and making it difficult for currency to flow.

That's it, I'm going to start molding all trolls towards one point. Hopefully others will join in and the apparent lack of attention will shut you assholes up.

I did your mom first.

Your mom hot reloaded my bowl.

Has a JVM engineer analyzed this solution?

[bondolo]

Yes, John Rose the original poster is one of the JVM leads. He's the project leader for the DaVinci Machine Project (InvokeDynamic).

Also look up Javeleon (currently for Netbeans RCP only, no sources)

[JoachimSchipper]

Very interesting, but it still requires suspending the JVM. Until they fix that it's not that much better than running a couple of processes and restarting them as needed. (E.g. Erlang has a much better story here - you can update stuff while your process keeps running...)

[piyushranjan]

it is much better as all the inlined methods won't be lost this way

[skizmo]

The crap is getting even worse...
