Take a look at Quicksilver (no longer active).
http://www.research.ibm.com/quicksilver/
"The Quicksilver project is exploring novel compilation models for Java.
Our goals are to support deep analysis, aggressive optimization,
testability and control over executables, all in the context of a fully
compliant Java system. Our prototype is implemented within the Jalapeño
compiler project."
