The Java version used by Eclipse is currently hardcoded because it 
doesn't compile with all the (older) JDK6's out there. I guess nobody 
has tried to use JDK7 to compile and run eclipse so far.

You can easily try the "run" part: set JAVA_HOME in your environment to 
/usr/local/openjdk7 and start the /usr/local/bin/eclipse (or 
eclipse-devel) script.

As to "compile": set JAVA_VERSION to 1.6+ in eclipse-devel/Makefile (I 
don't think this will work with the main eclipse port, as it is still at 
3.6.2) and rebuild. If OpenJDK7 is your default Java version, it should 
be picked up automatically.

Note that you can always specify a JRE for your own projects in the Java 
preferences. JDT support for JDK7 features will arrive with 3.7.1 (due 
end of September, I think).
