I know there are a bunch of JVM's. Just trying to make the point that for most people in most organizations, there's really no choice in the matter, leaving only Oracle's JVM or the OpenJDK - due to the weight of potential compatibility issues, need for retesting, uncertainty about future support/viability, etc. That's a large organization for you, I'm sure it's different at smaller shops and I can envy that.
