In installer it shows around 120 MB require space while in actual
public JRE take only around ~70 MB.
I suspect it is showing the same as JDK space requirments(as it also
have 120 MB require space) while JDK
consist of SDK+Private JRE+Source code+Demo


Steps to reproduce:
1) Launch JDK installer
2) Select "Accept" in license agreement and click on "Next"
3) Now click on feature "Public JRE" and see in description
   it says, it will require 120 MB of disk space.
   (Consider attach image: public_jre_space.png )
4) Now click "Next" and wait for JRE installer to get launched.
5) Once the JRE installer is there, have a look at space requirments
   it is far low than what SDK installer quoted, this can lead user
   not installing the public JRE just because of this wrong figures
   shown.
   In JRE installer following are the space requirments shown
   J2SE Runtime Environment: 65 Meg
   Support for additional langs: 18 Meg
   Additional font and Media support: 6 Meg
   So maximum of 89 MB.
