Summary:
Kotlin has an experimental support for [JSR-305 custom nullability
qualifiers](https://github.com/Kotlin/KEEP/blob/master/proposals/jsr-305-custom-nullability-qualifiers.md).
Annotating Nullsafe in a special way makes kotlinc recognize it as
such custom nullability qualifier and therefore treat types coming
from Nullsafe Java classes **not** as platform types, but rather
proper nonnull/nullable, which affects:
1. Generated bytecode (more thorough null-checks).
2. Type inference in the IDE.
NOTE re: p.1: one might expect that with properly annotated Java code
Kotlin would avoid inserting runtime checks. This is not how
Kotlin-Java interop works - in reality Kotlin does even more runtime
checking for Java code annotated as Nonull, which IMO is a good
thing, since you can't trust Java anyway.

Summary:
The @NonNull annotation, with camel case, can now be used to inform Eradicate that some fields that are not initialized by the constructor can be initialized by other means, e.g. via dependency injection.
Summary:
This test was actually testing: "at least one Field not initialized error is found" where we actualy want to test "exactly one Field not initialized error is found". The case of @Inject was also missing from the tests.
