I'm a Pythonista working on Groovy (and Grails) and I have a similar complaint about the error messages given by the Java stack. Groovy is one hell of a groovy language but the Java error output that it gives is comically long, and overall pretty useless. I rely almost exclusively on log output and step debugging.<p>To J_Baker's point, no you don't get used to that kind of thing, it's still annoying after 3 months to have to scroll through 2 pages to find a single reference to a method you were working on, and then it's not even the line where you had the problem.
