There is an argument that the JDK should read $HOME first but changing it after 20+ years could be risky, probably difficult to get a list of configurations/environments where the two might yield different locations. So I think the approach is reasonable. Even if "/" were a configured as the home directory in the user entry then $HOME would need to agree so that I think the <2 check is okay too. ------------- PR: https://git.openjdk.java.net/jdk/pull/7534
