JDK9 problems: ExceptionInInitializerError with sun.misc

[n2o]

As it is common with current Clojure tools, omnia has a problem with JDK9. It works as expected with JDK8, but when I switch to JDK9, it throws some errors.

λ java -version
java 9.0.1
Java(TM) SE Runtime Environment (build 9.0.1+11)
Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode)

Starting omnia results in the stacktrace below. There are problems with sun.misc which might be the source of this problem (described in this issue).

λ omnia
Starting Omnia 0.1.0..

Oh, how I feared this day would come.
Needless to say, very kind of you to report this.
I'll regressively take a look at each of omnia's dependencies and see if I may be able to find a solution.

EDIT: I shall put a notice in the README until this is fixed.

[AvramRobert]

Fixed with new release
