If I add the JUnit @Ignore annotation to my test class at the class level (rather than at the method level) and then try to run an individual test method from that class using "adb shell am instrument" and the "-e class com.example.MyTestClass#myTest" argument, I see ATSL crashing with the following stack trace.

This is using version 0.5 of the runner artifact.
