I was looking into why the patcher for the jdk installer was 18MB. It shouldn't need to be this big.
Instead of linking up the rtpatch .rtp binary diff file in both English and Japanese, we should only do it for English. We can consolidate this for both the JRE and the JDK using the PatchInstaller.rc resource file.
With this change, we can reduce every 5.0u7+ JRE download by at least 2.2MB, and we can reduce every 5.0u7+ JDK download by at least 9MB.
