From the source history, it appears that with JDK9 we dropped support for msys:
http://hg.openjdk.java.net/jdk/jdk/rev/2a2e56f4c03b This was committed about 1.5 years ago - are you suggesting that perhaps we added support for msys2 later on (perhaps unofficial or undocumented)?

If anyone is currently using msys to build OpenJDK, I'm curious to know what version so I can replicate that environment. As we are trying to add WSL support, we are touching all sorts of places in configure, and there is a big risk that we break the existing msys support. I would like to be able to setup an environment so I can at least do basic verification of such changes. I know we initially set this up for msys, but later I tried msys2, which seemed a lot more modern and easy to use. I do remember there were several options on how to setup it up exactly though. /Erik
