--why I advise someone download and install a proper Sun JDK from Oracle
and put it in a private location, then link Eclipse up to it instead of
using the one already on your computer host which gets (and should get)
updated from time to time. I even have two or three different versions
of Java in support of projects where I need that sort of thing (though
this is less common in work I do now).
Preferences -> Java -> Installed JRE does not affect the JRE Eclipse
runs on (which should be specified via the -vm option in eclipse.ini).
