Diagnosing ExceptionInInitializerError from Deamon

running my build with a probably unsupported JDK version gives me a: java.lang.ExceptionInInitializerError (no error message)
from the daemon. And no further details. I tried with --no-deamon, --debug and -S and such, but no success. Is there any way to get further information about the underlying problem?

if there is no way to get more information I guess I would turn this into a feature request then
