That's just not true. I checked out the source code because I was curious; it's ‘only’ 7.9M loc. I would guess that somebody slipped an extra 0 in there by accident (though I'm still not sure how they got that number, because the true tale is smaller than 7.96M).
That number (79.6 MLOC) is gained by adding together all the projects that participates in this release, which is far more than just the Java IDE. For example the Eclipse Platform which all the Eclipse IDE's builds on top of. Now if you look at just one of the five git repositories that is part of the Java tools, eclipse.jdt.core, you will get 1,597,008 lines of code.
