Ok im wondering where does xamarin get this path from?

Severity Code Description Project File Line Source Suppression State
Error The specified task executable location `"C:\Program Files (x86)\Java\jdk1.7.0_71\\bin\javac.exe"` is invalid.

So I can go and change it to the new jdk1.8. I have the new JDK set up I just need to know where to change the path at.
