Yep. That's true.
According to my tests we have to this for compiled mode of several 
combinations:
	OpenJRE-8 on arm
	OpenJDK-7 on aarch64
	OpenJDK-7 on x86
	OpenJDK-7 on x86-64

All of them fail with "Incorrect mode" and therefore have no compiled 
mode/JIT built in.

Although (to be honest) I haven't looked into the JDK-7 problems... 
AFAIK they should be fixable (at least for x86{,-64})...

Maybe someone else here on the list (like Henning, Maxin or Otavio?) has 
more information/background on that?

It's already on my todo list for tomorrow ;-)
