Error in Siddhi tooling 5.1.2 in Docker when application stopped and started again

[xtrmstep]

Hi,

Very often I'm getting the following error while stopping and running again my Siddhi application in the tooling. Topic name doesn't matter. The error is disappearing after several stop/start cycles or hard restarting of the container with Siddhi tooling (and applications).
