Looks like you've hit a bug in Dalvik's annotation processing code. I
suspect it's the same as http://b.android.com/5964, which found that
annotations with arrays of primitives were not handled correctly.
However, that should be fixed in 2.2 (Froyo), so it's strange that you
would be seeing it there as well.

Here's the converted stack trace:
