I tried it and found that it leads to a less clear exception message. `JNI_OnLoad` is called from `System.loadLibrary`, which turns any exception into an `UnsatisfiedLinkError` without using the message of the caught exception. So instead of a runtime exception with the message `Unsupported macOS version`, we would get something like this: Caused by: java.lang.UnsatisfiedLinkError: no glass in java.library.path: ------------- PR: https://git.openjdk.java.net/jfx/pull/567
