When Idea copies my *.properties (and other text files) after compilation it changes the encoding from UTF-8 to the system default (more exactly the the default encoding specified in the IDE settings).
PLEASE KEEP YOUR HANDS OF MY RESOURCE FILES.
I need them in exactly the same way they are. Nowhere in the documentation it says that Idea processes my resource files ("Each file ... will be copied to the output directory.")
In general 4.5 has a lot of features I appreciate, but I had much more pleasure developing with 3.0: Performance often is inacceptable. Features introduced in 4.0 still are not working well (refactoring with modules, column mode selection, etc., etc.).
I find myself spending time and time again on working at Idea's settings and limitations instead of working on my code. ]]>
So, please do a couple of 4.5.x builds before devoting all work to super duper new features in 5.0.
