Re: [cross-project-issues-dev] Upgrade of JDK8 on build server

[Stephan Herrmann <stephan.herrmann@xxxxxxxxx>]

I still recommend against compiling at source level 1.7 using 1.8 libraries.
The main reason still being: 1.7 compilers cannot understand default methods.

When I raised the issue at JavaOne 2012, all Oracle folks seemed to agree
that this is a non-issue (this situation should simply be avoided).

A few weeks ago, I saw the first vague explanation of what magic javac
indeed applies at -source 7 to gracefully handle default methods in
libraries. I'll try to update our compiler to do the same but after idling
more than a year due to lack of input, the schedule for the last few weeks
is very tightly packed. Hence no promise made on this issue...

best,
Stephan
