Something seems to be telling your compiler to expect some older
source.

If you have the "JDK 1.6" installed, I'd expect "javac" to be the
jdk's javac, not eclipse's.

At command line (assuming bash - start one, otherwise), enter
  type -all javac
and see, which paths all contain a javac, and which of them 
is first one.

If you see some common path, like /usr/bin/javac, then also do
an "ls -l /usr/bin/javac" to see, if it happens to be some symlink
to somewhere else.

Of course, there's also the question, of what *seemingly irrelevant*
(you surely have thought about the others, already) changes you
have done to the system *before* you first noticed the error.

Even with eclipse's javac, you could try explicit   -source 5
option to see if that would override any other defaults.

But more likely, some change caused a reordering of the javac's
found on your system.

You shouldn't do that.  I'm counting on Lew & others to explain
better, in how far this is really a bad idea...
