FWIW I agree. Some of us were chatting about this on IRC, and not only are these "VM" interfaces more often than not platform interfaces (or with some things, all they rely on is JNI and standard C), but they do lead to performance hits (witness our direct ByteBuffer). I think putting some design thought into this is a good idea, because right now I don't think we have any clear idea about what the scope or purpose of VM/platform interfaces are. Right now, it looks like it's just an ad-hoc catch-all for anything that can't be done in pure Java -- you slap a VM class on it, and hack up the core class. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iQEVAwUBROIpJuRILCRAfKHCAQIX5wf/aog1Jk+M1HNBKd7HZ6vzciTuPAynvlZ+ U+v7fvGI4FWaoCMUidB3rwov+gJhTXFpJpBy7ytGRExgpaJNp2Mp3kDpUJiInwYs pGh4rmzPvEd8dgkRyL7e4ccBF9ze7Ix7DzhXsldgNypOBDN+Bs7e1A9PjClnxQN8 t84Ii6YKeiifusAPRtgkmsS1wKF4PbCZ7YOdtT/BI6PfaERpgI4V/EnKASwx5Zp2 Z43NGTi/vvRb+qeOFbfhs8XA41EK5eb7ODDD6+W88PKcPUGLgaDlWHCP92XZdrS2 I/K4Ca9vluGs94WcMaflz7dFv9ofko4s9LmygqTIY+I8BKaXz2jTTw== =V2jF -----END PGP SIGNATURE-----
