I don't need a lesson on this.  I wholly agree.  IntelliJ keeps doing that automatically.  I've tried to change the settings but it still does it sometimes.  I hate it.  When I catch it doing it, I put it back.

I'm new to IntelliJ and I like it, but there are still some things it does that are frustrating.  I've been a Netbeans user for years, but it doesn't have aspect support.  STS is another one that aspect support, but it crashes all the time.  The last few releases have been horrible.  So I've switched to IntelliJ for stability and aspect support.
