Screenshot of error popup

While debugging an Eclipse Runtime Workbench process I am frequently getting these errors (from the Eclipse 'host', not the runtime workbench itself).

They cause an annoying popup which is very disruptive. It gets so bad sometimes that I can no longer do anything as a new popup appears as soon as I dismiss the previous one. This renders my Eclipse unusable until I stop the debugged process.

I am not sure what exactly the trigger is but I suspect it has something to do with frequent changes in the 'Debug' view, such as might for example happen when the process you are debugging creates and destroys threads frequently (i.e. number of threads in the debugged process going up and down a lot and frequently).

This is the error from the Error log:
