Eclipse keeps auto formatting upon save, for example: it is insisting the following code should be in a single line once I save, despite breaking it up the way I want to.
Just wanted to add a tip. If you want to avoid the line wrapping you can simply increase the "Maximum line width" value to something enormous. As long as that is sufficiently high eclipse won't do any wrapping.
Preferences > Java > Code Style > Formatter > Edit > Line Wrapping > Maximum line width
