GeoWave applies a formatter to all source code as part of the build process. The intent is to ensure that all source code is formatted consistently (which minimizes the pain of reviewing pull requests, examining diffs, etc.).

For some reason the source code is currently being formatted differently when GeoWave is built on Windows vs. OSX (PC vs. Mac). Also, the build flag -DskipFormat=true should inform Maven to skip formatting, however this flag seems to be ignored on a Mac.
