Netbeans "Cannot locate java installation in specified jdkhome..."

If you change the jdk's dir path after Netbeans installation, the Netbeans will complains it cannot find the original jdk's path and ask if you'd like to use "default" jdk in a message box each time you start the program.

To disable the warning message box, just change the default jdk path to the new one Netbeans at "<netbeans_dir>/etc/netbeans.conf":

netbeans_jdkhome="E:\Java\jdk1.6"
