> The Executor may fail when trying to mmap a file bigger than Integer.MAX_VALUE due to the constraints of FileChannel.map (http://docs.oracle.com/javase/7/docs/api/java/nio/channels/FileChannel.html#map(java.nio.channels.FileChannel.MapMode, long, long)). The signature takes longs, but the size value must be less than MAX_VALUE. This manifests with the following backtrace:
> java.lang.IllegalArgumentException: Size exceeds Integer.MAX_VALUE
