Hi Thomas, It is called at the loading of the page but the HtmlUnitThread only runs while that call is blocking...
I'm struggling to point the finger at a particular line of code but: * Fiddling with the number of seconds GWT specifies to HTMLUnit can make the problem appear and disappear (a colleague has duplicated but I had to mess with Maven dependencies so not as reliable at test as wanted) * I noticed that when a test stalls the HTMLUnit JavaScript thread was "gone". I'll try and write a unit test before raising an issue but is not easy as seems non-deterministic. btw Congratulations on your new role in the steering committee. Bit scary as the code as been sooooooooo good so far but fingers crossed.
