      Description

        Currently all the jar/zip files are mmaped to the address space of java application. Customers are complaining about the huge perceived footprints. One way to workaround this is to mmap part of the jar file or read it from disk.

        Expriments show this could reduce percieved footprint by more than 100% on Solaris and more than 30% on Linux since rt.jar just takes too much space.
