We need to fully support a silent JDK install in 6u15, which should also install the public JRE and Java DB.
Now that we own our JDK wrapper code, we can fully support silent installation. If the public JRE feature is on, it should create a registry. The wrapper should check that registry after running the jdk.msi, and it should run msiexec on the jdk$version/jre.msi, and then it should remove the msi/mst files.
I've read in forums that Java DB might not currently be getting installed with JDK silent mode, so we need to look into this as well.
