In practice, it doesn't make much difference.

You install the JVM once and rarely upgrade it.

You build and distribute your Java apps as fat jars (meaning, all dependencies bundled.)

But what happens when some of the apps require different versions of the JVM?

[bitmapbrother]

As long as you're using the latest version then this shouldn't be a problem as the JVM is backwards compatible.

Except on those fun occasions when it isn't really. :\

You know you can have multiple VMs installed, with different JAVA_HOMEs, right?

This is a solved problem.
