I think the second style is more readable, so would advocate using that.
As you say, the readable macros are set up using the PORT_ACCESS_FROM_*
directives, so that you can use them if you are passed different types.
PORT_ACCESS_FROM_ENV(JNIEnv) - you have a JNIEnv struct ptr
PORT_ACCESS_FROM_JAVAVM(JavaVM) - you have a JavaVM struct ptr
PORT_ACCESS_FROM_PORT(portlib) - you have a portlib ptr
