This check is also performed when abstract type members become concrete (aka a "type alias") -- then tparams.length==1 (checked one type member at a time -- in that case, prefix is the name of the type alias)
Type application is just like value application: it's "contravariant" in the sense that the type parameters of the supplied type arguments must conform to the type parameters of the required type parameters:
e.g. class Iterable[t, m[+x <: t]] --> the application Iterable[Int, List] is okay, since List's type parameter is also covariant and its bounds are weaker than <: Int

A creator for existential types.
A creator for existential types. This generates:
tpe1 where { tparams }
where tpe1 is the result of extrapolating tpe wrt to tparams.
Extrapolating means that type variables in tparams occurring
in covariant positions are replaced by upper bounds, (minus any
SingletonClass markers), type variables in tparams occurring in
contravariant positions are replaced by upper bounds, provided the
resulting type is legal wrt to stability, and does not contain any type
variable in tparams.
The abstraction drops all type parameters that are not directly or
indirectly referenced by type tpe1. If there are no remaining type
parameters, simply returns result type tpe.

The raw to existential map converts a raw type to an existential type.
The raw to existential map converts a raw type to an existential type. It is necessary because we might have read a raw type of a parameterized Java class from a class file. At the time we read the type the corresponding class file might still not be read, so we do not know what the type parameters of the type are. Therefore the conversion of raw types to existential types might not have taken place in ClassFileparser.sigToType (where it is usually done).
