java headless exception error on MacOS 10.13.1 #5

Hello, I installed the Crossover package and its dependencies from CRAN. However, when I run CrossoverGUI(), I get the following error:

Error in .jnew("org/mutoss/gui/CrossoverGUI") : 
  java.awt.HeadlessException
2017-11-30 15:15:03.072 R[511:4469] [JRSAppKitAWT markAppIsDaemon]: Process manager already initialized: can't fully enable headless mode.

I'm running OS 10.13.1 and R 3.4.2. My java version is:

java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode)

I searched for "Process manager already initialized: can't fully enable headless mode." errors in google, but found nothing obvious.

Any ideas?

Thanks, -Bradley

Dear Bradley, this is a known problem for many packages using rJava and OS X. The only known workaround to me is to start R via JGR on OS X. Best regards, Kornelius
