How to get parameter type at call time?

[TiddoLangerak]

Consider:

class A {
    public <T> void foo(T value) {}
}

class B {
    public void bar() {
        new A().foo("string");
    }
}

With a DescribedPredicate<JavaMethodCall> I can get a reference to the call to A.foo, but it appears that the JavaMethodCall object only contains type information defined in the method signature. Is there a way to get access to the type information at the call site? I.e. that we're passing a String to the method?

This is somewhat related to #721, but subtly different: I'm not looking to get the call value (which isn't generally statically available), but I'm looking for the call type (which is statically available).
