The current size of the Merlin SDK is 47MB, which is very large. It would be nice if we could get it down to a reasonable size. We currently bundle up 2 jre's. One is located in C:/jdk1.4/jre and the other is the bundled j2re1.4-i-win.exe that we package up and call silently. The c:/jdk1.4/jre directory has everything that the j2re1.4-i-win.exe has and is basically a superset of it. A solution would be to just copy it over to C:/Program Files/JavaSoft/JRE/1.4 after installation instead of calling the jre silently. This will require more work in the jdk install script because the public jre registries will need to be created during the jdk install, and plugin and webstart will now have to be installed with the jdk install. After copying over, we will also have to remove the files in the public JRE that didn't exist there before. We will also need to bundle up the jre uninstaller log file with the jdk, so we can still have separate uninstalls for the sdk and the jre. There are a few other things, but the basic goal will be to get the footprint download size down, while keeping the same final product.
