Action: Edit the System message, saving, then pressing the browsers back button, editing the System message again.

What Happened: The system messages were all edited correctly, but then gradle builds started failing. Using the Config History plugin I could see that (and retested) when using the back button on the browser, it inadvertently changed all the Gradle Installer versions! So Gradle installation with name '1.6', was actually downloading the 0.7 installer.
