There are couple of issue which should be addressed
1.) JDK installaer shouldn't start if minimum disp space is not available
2.) It should calculate the total disk space required for all the features selected by user. As user may select unselect some of the features offered by JDK.
3.) If JDK installer fails to install for some error, we should clean the installation directory and files.
