I guess it's a matter of naming convention. What I tried to make the CompilerConfig API about is to check if compilers are present/enabled and in which combination. Of course presence of a compiler implies that we're going to see nmethod produced by it. I'd like to keep the current naming if it's not a huge eyesore for you. ------------- PR: https://git.openjdk.java.net/jdk/pull/1985
