No, you’re being facetious. GDB and jdb are not comparable at all. jdb is not meant for actual use. This becomes immediately obvious if you spend like ten seconds with it. There’s no readline support, no tab completion, no fancy breakpoints, poor expression evaluation…I can go on and on. GDB has a learning curve but is unquestionably a professional tool that sees heavy use. Similarly, people can make also sorts of spaghetti projects with C(++) but you can also make very nice ones. With Java the state of the art basically requires you to juggle a classpath at all times. You surely know this: all the tools are designed to be driven by automation. Why are you claiming otherwise?
