well yes... it's a learning curve and it takes a while but if you are familiar with the jvm and xml and to some degree spring-framework and reflection it's usally pretty easy to find a root-cause - you also have great tooling like async-profiler or just sending `kill -3 <pid>` to get a stacktrace. At least you've got a hill to climb upon instead of an empty field.
