If I want to have arithmetic-overflow checking in all parts of an

Id like to clutter the code as little a possible...
Is there any way to instruct the JVM to include it?
Nope, can't be done. And yes I've griped about this myself, so you're
in good (well, average at least) company.
OK...
What about patching the JVM to add this (sadly missing) "feature"?
It is open-source, isnt it?
There are a few open source JVM's around.
Nobody has done this already?
I don't think so.
And remember that it will not be Java or JVM any longer.
Doesnt seems like a terribly big project, once I can locate the right
place to do it...
Probably depends a bit on how you want it to work.
Any license aspects to consider, if I do it myself?
You need to follow the license for the open source code.
If I remember correct then OpenJDK and GCJ is GPL and Harmony
is Apache (for the JVM part).
And you can not call it Java or Oracle's lawyers will demand
10 trillion dollars (or something like that) for trademark infringement.
