Java DB is to be removed as an optional feature from the Windows 32-bit and 64-bit JDK installers. The Java DB MSI installers will no longer be used.
There will no longer be a checkbox to not install Java DB in the JDK installer GUI.
Command line installation will no longer support "JavaDBFeature" as a parameter for ADDLOCAL.
JavaDB can already be found in the db directory under the JDK installation (e.g. C:\Program Files\Java\jdk1.7.0\db\ ) where it is always installed.
The db directory is not optional. It will be installed by default with no option to not install it.
