Ensure that local type variable declarations work for methods

[cowtowncoder]

(inspired by [JACKSON-468])

We need to add unit test to ensure that methods like:

public T getValue() { .... }

can be resolved (including cases where there are other type bounds). And obviously if (when?) there are issues, fix these.

Added a unit test to verify that this is handled correctly (included bounds checks)
