Support for more generics in methods:

[slany]

Follow mapper not working yet:

abstract public <T extends Data2> T conv2Data2(Data1 test, T ret)

[slany]

Temporary solution for Kotlin (in jam source code):
// #28 - remove not supported constructions "? extends "
resolvedType = StringUtils.replaceAll(resolvedType, "? extends ", "");

[slany]

Adept for final solution:

types in method api on overrided methods is with "? extends ", bud every implementation is without it

// source in java
abstract public List<? extends Obj2> conv(List<? extends Obj> values)

is transformed to generated code:

@Overrided
public List<? extends Obj2> conv(List<? extends Obj1> values) {
    List<Obj2> value = new ArrayList<Obj2>();
    // ...
    return value;
}
