@Pattern annotation not calling PatternRule.isValid()

[ben-xx]

@NotEmpty
@Pattern(regex = "[0-9]+")
@Bind(R.id.fence_add_latlon_edittext)
EditText mFenceAddLatLon;

(note: using ButterKnife for binding widgets)

@NotEmpty annotation calls isValid() in NotEmptyRule.java, but @Pattern never calls isValid() within PatternRule.java.

Using 2.0.3

Sorry, looks like the issue was on my end with Android Studio 2.2 Instant Run not picking up Annotation changes in .java file.
