// we did not do.

// 2) The sample code provide at the top of the doc doesn't even call JNI_GetDefaultJavaVMInitArgs.

// 3) The Oracle documentation for Java 6 through Java 8 all contain a comment "Note that in the JDK/JRE, there is no

// marked it deprecated.

// Omitting the call to JNI_GetDefaultJavaVMInitArgs works fine on Mac and Linux with Java 7 and Java 8.
