Install true 64bit JRE (with Java plugin and Java webstart) on 64bit OS, start Java control panel from system control panel, the following exception will be show in a dialog box and Java control panel will failed to load:

Could not find the main class: com.sun.deploy.panel.ControlPanel. Program will exit.

EVALUATION This issue is caused by bug fix 6710203 in 6u10 b31, which is trying to link msvcrt71.dll in WinConfig.java, unfortunately, there is no msvcrt71.dll in 64bit OS and we are not shipping this dll in JRE/bin directory as well, a link exception will be thrown which cause Java control panel exit.
