Sort of. That code has changed quite a bit - UseROPProtection now is a string field not a bool. "none" or not set - pac disabled. "pac-ret" - pac always enabled "standard" - pac enabled if the cpu+os support it. Also, the pac instructions used aren't all in the NOP space. So, it will crash on a non-pac machine. It might be possible to change it so it does only use nop space instructions, but I don't think it'll be optimal (need to double check). ------------- PR: https://git.openjdk.java.net/jdk/pull/6334
