IT factor! Am I on a fashion website now? What kind of argument is that? Also, why on earth would you use strace or gdb for Java? It has enormously performant debugging tools in the JDK. Also, IDE debugging integration is second to none.

"It" factor affects talent pool size. If you're planning a large project and want to hire talent to staff it, how popular a language and framework you choose to implement it in has a direct effect on the cost of implementation. Hint: popular languages and frameworks are far easier to hire for than obscure ones, so unless you have a VERY GOOD REASON not to, it's best to choose a popular language.
