[jvm] using generic functions

[ianharrigan]

So im prototype working with FHIR in haxe, and would hopefully be able to generate libs from haxe that could be used in other languages (js / java initially), however, i hit a stumbling block. Im not 100% sure if its a bug or if its my usage, but, here goes:

@:expose
class TestObject {
    public function new() {
    }
    
    public function testSomething<T>(clz:Class<Resource>):T {
        var t:T = cast Type.createInstance(clz, []);
        return t;
    }
}

Then in java, ive tried to do the following:

TestObject t = new TestObject();
Patient p = t.testSomething(Patient.class);

However, it tells me:

Main.java:16: error: method testSomething in class TestObject cannot be applied to given types;
        Patient p = t.testSomething(Patient.class);
                     ^
  required: Class<Object>
  found: Class<Patient>
  reason: cannot infer type-variable(s) T
    (argument mismatch; Class<Patient> cannot be converted to Class<Object>)
  where T is a type-variable:
    T extends Object declared in method <T>testSomething(Class<Object>)
1 error

Digging around a little i think its because, the testSomething function signature (in java) is:

public <T> T testSomething(java.lang.Class<java.lang.Object> clz)

And following the Patient class through it ends up as (again, in java):

Patient -> DomainResource -> Resource -> haxe.jvm.Object

and im assuming haxe.jvm.Object is incompatible with java.lang.Object?

Any thoughts on how to achieve this?

Thanks in advance, Ian
