Yes, sorry about that. The issue is that the C runtime is statically built into lwjgl.dll and its version must match the one used by glfw3.lib. The build server uses Visual Studio 2015 for everything as of build #15. I'm not sure if there's something I can do about this, will look into it tomorrow.
In the meantime, you could build GLFW locally and use that. Set LWJGL_BUILD_OFFLINE=true before linking LWJGL, otherwise ant will override your local glfw3.lib.
