Metal rendering pipeline crashes on virtualized OS

        Under virtual machines, JFX for OS X selects SW rendering as the default because OpenGL is not supported.
        JFX 25.0.2 started including the Metal rendering pipeline as a second candidate to be probed. However, it seems that Metal is not supported either, and instead of switching to the software renderer, it causes the program to crash.
        ```
        * thread #22, name = 'Java: QuantumRenderer-0', stop reason = signal SIGABRT
          * frame #0: 0x00007ff80d55dc52 libsystem_kernel.dylib`__pthread_kill + 10
            frame #1: 0x00007ff80d597f85 libsystem_pthread.dylib`pthread_kill + 262
            frame #2: 0x00007ff80d4b8b19 libsystem_c.dylib`abort + 126
            frame #3: 0x00007ff81883cf26 Metal`-[MTLIOAccelDevice newIndirectArgumentEncoderWithLayout:] + 9
            frame #4: 0x00007ff81887f35c Metal`-[_MTLFunction newArgumentEncoderWithBufferIndex:reflection:functionReflection:] + 364
            frame #5: 0x0000000100877a10 libprism_mtl.dylib`___lldb_unnamed_symbol649 + 432
        ```
        The workaround would be to select the software renderer manually
        ```
        -Dprism.order=sw
        ```
