This problem is happening for me too now my kids have two accounts and have been running Open to LAN games. Host Computer: OS X 10.11.1, Minecraft 1.8, Launcher 1.6.44 This is the one usually running as the host when it hangs.
Sorry. My mistake the problem was resolved by updating graphics drivers. The issue is that mine raft failed to start with a stack trace related to missing OpenGL components. The only fx would be to catch the exception and provide a better error message.
