Bill tracked down this problem to a difference in windows isatty behavior from other platforms. The change to suppress the prompt was required in some use cases and isatty was used for the decision. It fails in windows which is why the new jconsole for 901 has the problem with emacs on windows.
We have added a new command line parameter (-prompt) to jconsole that requests the prompt. Please download new jconsole.exe and install it in your bin folder. Then add -prompt to the emacs start of jconsole. https://www.jsoftware.com/download/jengine/j901-release/windows/j64/jconsole.exe Please let us know if this fixes the problem. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
