using JavaArgs from JavaLauncher throws error

[Gary Adams]

If you look in jdk/src/java.base/ios/native/JavaLauncher/JavaArgs.m
source file you'll see several init functions that are layered.
It was originally designed to be able to swap between different properties.
e.g. initWithDebug could take release or debug property files, which calls
into initWithProperties.

If you add JavaLauncherArgs.properties file to your xcode project and
deploy it into your bundle it will be read & parsed when you call init. e.g.

JavaLauncherArgs.properties:
   appArgs= ...
   mainClass= ...
   jvmArgs= ...

If you bypass the init calls you can use the explicit calls to 
addJavaArg and
addAppArg. See the JavaArgs.h for some additional information. There
are some doxygen comments in the header files.

There are some tools and template projects with some better use cases, but
they still need to be updated for jdk9 before they are ready to be pushed.
