There aren't that many problems with the JVM compared with Java. Most of what makes java suck is the language and what makes the performance sluggish is the standard lib as well as the programming style the community encourages.
As much as I love to rag on java the language the JVM is generally a solid piece of work that makes reasonable tradeoffs.
