Project Leyden addresses Java pain points
See the original posting on JavaWorld
Long-term Java pain points including slow startup time, slow time to peak performance, and large footprint would be addressed by a proposal being floated in the OpenJDK community by Mark Reinhold, chief architect of Oracles Java platform group.
Called Project Leyden, the proposal would deal with these pain points by introducing the concept of static images to the Java platform and the JDK. A static image is a standalone program, derived from an application that runs that application, and no other. A static image is also a closed world that cannot load classes from outside the image or spin new bytecodes at runtime.
