I’m not immediately able to reproduce this but it looks below like you have worked around the problem.

You are right, this is an error and I’ve reported it as internal bug #47868. It appears by the fact that you got further than you found the workaround, using an instance of GsNetworkResourceString.

This is a known bug (internal #47663). The work-around is to use different stone names.

When I try your example with two Jade sessions on the same GS 3.4.3 stone it returns a string describing the stack. What IDE are you using? What sort of dialog does it open? Can you provide a screen shot?
