Javadoc hover for parameterized method with insufficient context

[eric-milles]

Consider the following:

@groovy.transfornm.TypeChecked
void test() {
  def list = Collections.emptyList()
}

Insufficient context exists to determine the list element type. Static type checking produces an "unresolved" type variable #T so list has an inferred type java.util.List<#T>. Code hover for list and emptyList fails to display due to error in method signature (see below).
