When commits are made, reformatting the file in addition to the core task covered by the commit makes it very hard to review the changes because of the "noise" it creates.

Reformatting all java files once and for all would simplify code review.

This can be accomplished by automatic tools (such as IntelliJ) and should have a minimal impact on the stability of the application.

 Since all java files could potentially be impacted by this change, this might potentially force all concurrent change requests to be rebased.
