[jbosstools-dev] Java 8 experiment for JBoss Tools 4.3/Developer studio 9

[Nick Boldt]

Actually, I should clarify. Seems that the BUILD may be ok w/ a lower 
JDK than the BREE specifies, but Surefire TESTING will surely NOT fire 
with the lower one, because the lower runtime environment is not 
compatible. And any "installation-like" step (like installing plugins 
into an update site build) will likely fail too.

But to your question, "how we can make the installation require Java 8, 
but not require it at build time?"...

I counter: "Given JDK 8 is everywhere (RHEL6.6, 7.1, Fedora, Ubuntu, 
Windows8, OSX) why can't we just build with the new standard baseline? 
Why encourage people to build w/ the EOL'd JDK 7?"
