The JNI interfaces between the Java code and native libraries is not stable, such that a mismatch between the Java code and the native library will result in undefined behavior, often leading to a crash or unexpected exception.

We should include the version number in each of the loaded JNI libraries and "fail fast" if it doesn't match the version of JavaFX from the Java code. Ideally this failure would be detected at load time is such a way that we would consider it a failure to load and try to load the library from another location.

See JDK-8223377 for the motivation for this RFE.
