A common thing I do is find the problematic code using the IntelliJ debugger, change the code, press Cmd+F9 to reload the function code, hit "drop frame" so the executing code goes back to the previous function in the stack (the caller function) so the edited function can execute again with the new code. While at it, you can also change the value of any visible variable and evaluate any expression in the context of the currently executing scope.
