Martin Kouba commented on WELD-1060:
------------------------------------

It seems that resolution works in case of type variable with upper bound.

See
*org.jboss.cdi.tck.tests.lookup.injection.parameterized.ParameterizedTypesInjectionToParameterizedWithTypeVariableUpperBoundTest.testInjection()*
and 
*org.jboss.cdi.tck.tests.lookup.injection.parameterized.ParameterizedTypesInjectionToParameterizedWithTypeVariableTest.testInjection()*

> * the required type parameter and the bean type parameter are both type variables and the upper bound of the required type parameter is assignable to the upper bound, if any, of the bean type parameter."
