Hi arun,
You could update to CF 9.0.1 + CHF4 + security patch.
9.0.1 update EXE from here:
http://www.adobe.com/support/coldfusion/downloads_updates.html#cf9
Cumulative Hotfix 4 from here:
http://helpx.adobe.com/coldfusion/kb/hot-fixes-coldfusion-9.html#ColdF usion 9.0.1 hot fixes
Security patch APSB13-13 and 27 from here:
http://helpx.adobe.com/coldfusion/kb/coldfusion-security-hotfix-apsb13 -13.html
and
http://helpx.adobe.com/coldfusion/kb/coldfusion-security-hotfix-apsb13 -27.html (note use 9.0.1 section 2)
Once CHF4 is applied Java 7 is supported so you might like to use that rather than EOL Java 6 as likely is current.

A CF 9.0.1 system information says:
Version 9,0,1,274733
Update Level /E:/ColdFusion9/lib/updates/hf901-00011.jar
CF 9.0.2 (latest build CF9) would be an uninstall and re-install using 9.0.2 installer.
HTH, Carl.
