Unfortunately that isn't the case. Java's JCE provider for it's random will read from /dev/random, if you happen to generate a lot of keys in quick succession (such as unit tests for a product) you will run out of entropy really fast, and tests will seem to take hours... Which really sucks because then you run something like haveged on the server running the unit tests because you can't have a build take hours because Linux takes forever to gather new entropy on headless servers :-(
