Hell, I'm fucking annoyed at anything that requires too much configuration.
configuring everything is a goddamn nightmare
Maven? Fucking nightmare! All the dependencies, and installs, and builds, and XML files, and setting the projects, and downloading, and... pisses me off. Specially since I can work out things in a much more simpler way by just linking "User Libraries" with Eclipse. Seriously.
JPA? Also mighty annoying. 3 or 4 hours of back and forth just so I can launch Eclipse's wizard so it generates class files from a schema. I don't even want to know how it would be like to do the annotations by hand (it probably is one of the definitions of masochism).
Databases are the same, some a bit more sane than others.
Web stuff is the pinnacle of configuration madness.
