I would vote -1.

This is what Max said:

Guys, we've supported running the installer with lower/non-JDK versions for years.

The page where you choose the JDK already limits/warns you about this if we can't find a matching JVM.

This is nothing new.

The installer should run on as low a version as possible IMO to increase likelihood of it being even
installable for users with less optimal java versions.

Just to make sure I just tried installing JBDS 8.1.0.GA running the installer with Java 6 (on Mac) and choosing Java 8 and it works just fine. I think there is no reason to limit this.

And as Max says, we already have checks in place on the installer page where you choose java - if you select too low of a java version, it will complain. So we can easily update this to require java 8.

And it helps with the use case Mus mentioned as well: Imagine a RHEL 6.6 user has both OpenJDK 1.7 and 1.8 installed, but 1.7 is the default (using alternatives). So it's desirable that such user can install JBDS without switching his default java version and he will just choose the right java in the installer.

Another use case is OS X: If you just double-click the installer jar, then you have no control over which java is used to run the installer - typically it will be the highest java installed, but it's somewhat unpredictable. So it's good that we don't restrict the installer, just the JBDS runtime.

> If we only support running the JBDS 9.0 IDE with Java 8, then the installer should prevent the user from installing with older versions of Java. Thx!
