Thanks!

It does make sense. Someday, I should check if these newer features
should be used in the generated code.

Luckily, nothing was needed.

That’s what I was truly worried about, thanks!
Thanks to Paul and you. I installed this in Bison.

java: bump to Java SE 7
macOS 10.14 no longer supports versions of Java earlier than 5.
And Java 6 will be deprecated by the end of this year. So let's move
our requirement to Java 7.
