Consider using java 8 for EAP 6.4 by default [ resolved making j7 default instead of j6]

Here's the problem that I just hit:
I added EAP 6.4 to JBDS 9.1 using runtime detection. Then I created the html5 project from JBoss Central using the EAP 6.4 server as target runtime.
Then on the project, I just Run -> Run on Server.
The server started, but deployment failed on Unsupported version: 51.0
Which is a bit strange, because the server was running with java 6. But anyhow. It seems the quictstart requires java 1.8 now. But default, EAP 6 will be set up to use java 6.

So ideally EAP 6.4 would use java 8 if present. But I know we discussed similar things in the past and there didn't seem to be any way to make something like this happen. But I just wanted to present this use case and perhaps there is some possibility?
