REG : Entering wrong value to accept the license agreement of jre/jdk installation doesn't respond

Tested platform : Solaris / Linux
Tested build : From 6U2 to 6U10

Steps to reproduce :
1. Install jre / jdk
2. After showing the license agreement there will be a question
"Do you agree to the above license terms ? [yes or no]"
3. Enter some value other than yes / no
Till 6U1, if the user enters wrong value other than yes / no, it used to keep on ask the same question.

From 6U2 onwards, if the user enters wrong value, it just waits there.
This is the regression from 6U2
