------------------------------------------------------------
[~reuvenlax] I was able to make this error go away by setting the project's SDK
to JDK 1.8 in the IDE.
If I set it back to 1.7 the error returns.
This behavior is consistent with the earlier findings where it compiled fine
using maven with the env's JDK set to 1.8 and failed to compile with the env's
JDK set to 1.7.
This leads me to believe people who have JDK 1.7 set as their default JDK will
not be able to successfully compile Beam at the moment.
