I am not sure what caused this as I updated a few things in the mean time, but debugging now gives me a popup saying Unable to open 'libintegers_patch.dart': Cannot read property 'create' of undefined. when it hits an exception. I have everything pretty much on the newest version, but I can send version numbers if you want.

Something changed about the debugging interface as well because now I can see some kind of file tree when I start the debugger. However, somehow the debugger no longer pauses on uncaught exceptions. Instead it quits and prints some error the the debug output. I get:

loading test/all.dart:

ERROR: Failed to load "test/all.dart":
The getter 'isNotEmpty' was called on null.
Receiver: null
Tried calling: isNotEmpty

{stack trace in my project}

This could very well be an error with the test or analyzer package, but I am not sure to track down where it it coming from.
