Hi all,
We had a problem in TL the other day [1] [2] that wasn't caught because a
developer was using a JDK 8 build as his boot JDK. Turns out the rule to use
JDK N-1 as the boot JDK for JDK N isn't specified clearly in
README-builds.html. Here's a diff to strengthen the wording in that file.
Also, is it OK if I push this into TL?
Thanks,
s'marks
