why am i getting a StackOverflowException when testing a GridViewPager with Robolectric

i'm trying to add a test for the activity in the android wear implementation and getting a stack overflow exception.

the test:

@Test
public void testActivityInit() {
       Robolectric.buildActivity(CustomGridActivity.class).create().start().visible().get();
}

the exception:

i've found various reference projects that test android wear, so the basics do work. it seems like the exception is in how the GridViewPager is handled/implemented. has anyone else run in to anything like this or have a fix/workaround?

thanks.
