I think that, when GP wrote "windows", they meant the operating system. And when they wrote "debuggers work well", they meant the quality of debuggers, not whether using a debugger is a good idea. Quality of Windows debuggers is generally on a whole other level than on Linux. Chromium DevTools also has a nice debugger. I don't know about Java.
