NetBSD is going through some similar security moves currently (extending PaX[0]), and iiuc, there are special considerations required for Java/jvm, because of the bytecoding process. Does anybody know if my understanding is correct (that a page will have to be both writable and executable) and if so, what are OpenBSDs considerations for this ?
