Looking at the relevant line it could be System.console() or the client field. Console.readPassword() can also return null on EOF but the tap call shouldn’t really care since it doesn’t dereference it.

Any chance of running in a debugger to figure out which one it is? I suspect it’s System.console() if you are running in some non-interactive setting.
