I use MyEclipse with a local app server quite often for debugging. I love how it can insert changed code into the JRE without restarting most of the time. When it fails to replace code, it used to alert me and give me the option to stop or restart the server. I must have checked the “don’t show me this again” box or something, because the dialog never appears, and I can’t seem to find out how to reenable it…
