It would nice if a compiled client against JDK 8 headers works without recompiling with a JDK 9 runtime.
To make really future proof; using a client compiled against JDK 9 with JDK 1X you will need some way to know witch version of the struct was used.

E.g. SetTransportConfiguration(&config, JDWP_TRANSPORT_CONFIGURATION_CURRENT_VERSION);

Thanks, Robbin!
