SignalR throws Exceptions in its own threads which aren't handled

[arnoldpistorius]

Hi,

It appears that the SignalR connection throws unhandled exceptions inside its thread. There is no way to handle them in my application except for defining a global Thread.UncaughtExceptionHandler. This also affects my own threads, so this is not really the greatest solution. The exceptions occur mostly when I call the hubConnection.stop() method. Below I have included an example of Exceptions thrown by the connection Thread (an IndexOutOfBoundsException is also thrown sometimes, I will add the stacktrace when it occurs again):

It would be nice if the exceptions inside threads are handled.

Thanks :)

Edit (added IndexOutOfBoundsException):
