using JavaArgs from JavaLauncher throws error

[Grigory Ptashko]

Gary, thank you.

I’ve managed to launch java both on the simulator and on the iphone 6s (arm64).


One more question. Is there a javadoc on the for openjdk9?
Especially, I’m interested in the documentation on jshell API.

I googled but did not find it. I alse looked at the jdk9 source tree but there
are no javadoc after building the jdk.

Thank you!
