[hibernate-dev] ORM 5.1 vs compatibility with Java 6

Is Hibernate ORM 5.1 still meant to be compatible with Java 6? The readme seems to promise that it should be, but it's not: I happened to try compiling it and it failed, as some recent changes are using JDK classes which have been introduced in 7. Turns out it builds fine for Andrea an Chris, as they don't have the JAVA6_HOME variable set: in this case the build will be lenient: log a warning and move on. I guess the same was done by all others on the team? CI is not checking this either. Wondering if you all feel like it's worth fixing branch 5.1, or if it's a dead branch anyway. Thanks, Sanne
