A new IDEA 15 feature is bugging me a bit. Every time I go into debug, a choice appears at the top of the editor that offers me 'Alternative source available for the class ...'. The choices I get are 1. The Java file in the editor itself and 2. the same class from the sources-jar on my classpath (Maven).
I'd rather not have that choice appear. It covers part of my screen and when I make any choice the editor moves back to the top of the file.
I haven't been able to locate a way to disable that in IDEA 15. I could also try to ignore it, but then the choice remains there as long as that Java file is opened in the editor. Ignoring such things is not one of my strong points :-)
