Java Kernel's footprint has increased by about two megabytes for common scenarios.  We need to investigate to determine where the size increase has come from and file additional CRs to resolve the individual issues.

EVALUATION UPX has been put back via 6612006. The 7-Zip(/GZIP{Input,Output}Stream support for bundles needs to be put in but disabled to confirm no regression and then enabled with CR 6601859 after making the compression optimizations compatible with the recently added time zone optimization (CR 6625963).

EVALUATION The main Wiki page for footprint analysis is here: http://j2se.sfbay.sun.com/web/bin/view/Deployment/KernelFootprint Implementation details for use of 7-Zip and UPX are here: http://j2se.sfbay.sun.com/web/bin/view/Deployment/KernelFileCompression

EVALUATION We have already made many changes to address this, but the remainder will come from the LZMA and UPX compression currently being incorporated. See CRs 6601859 and 6612006 for more details.
