Eclipse 3.6.1 is now placed in the archive. This means the mirror sites don’t bother mirroring it. The URL for the ecjsrc-3.6.1.zip must be updated to this:

src = fetchurl {
  url = "http://archive.eclipse.org/eclipse/downloads/drops/R-${version}-${date}/ecjsrc-${version}.zip";
  sha256 = "0xfsig2pzd9wy524wp11s7pc7cj81s28g1485995b44d9qbi17h8";
};
