Before editing, create a backup of the jvm.config file located in the {cf.instance.root}/bin/ directory. 
Open the file with a text editor to locate the line beginning with java.home= for example: 
java.home=C:\\CF11\\jre 
Change that line to the path of the new JRE, for example: 
java.home=C:/java/jdk1.7.0_XX/jre 
Note:  The path must use forward slashes / or escaped backslashes \\ otherwise ColdFusion will 
not start. 
Restart ColdFusion. Visit the System Information page of ColdFusion administrator to confirm that the 
JVM has been updated. To revert to the default jvm replace jvm.config with your backup and restart 
ColdFusion again.
