Steps: EXEC: go Preferences > Server > Runtime Environment > Add > JBoss 6.x Runtime > (Download Runtimes Dialog pops up) Download and install runtime... EXEC: pick JBoss 6.0.0 hit Next Result: The license cannot be displayed. An error dialog pops up instead that complains about an insecure connection One can still accept the license and have the runtime downloaded & installed. There's no real harm. Accepting a license that one cannot read is invalid though.
