PODAM fails to initialize MyType<T> containing final Map<T,T>

[Jordan Angold]

I have a test case that requires PODAM to create and fill a POJO containing a final Map<T,T> as suggested in the title, and found that it doesn't work. I'm using PODAM 7.0.5 .

I have distilled the problem down to this example:

public class MyTest {

@Test

public void test() {

PodamFactory factory = new PodamFactoryImpl();

MyType<String> wrapper = factory.manufacturePojoWithFullData(MyType.class, String.class);

assertNotNull(wrapper);

}

public static class MyType<T> {

/* // works:

Map<T,T> map;

public void setMap(Map<T,T> map) { this.map = map; }

//*/

// doesn't work:

final Map<T,T> map = new HashMap<>();

public Map<T,T> getMap() {

return map;

}

}

}

If you use the 'doesn't work' part, you get:

java.lang.IllegalArgumentException: java.util.Map is missing generic type arguments, expected [K, V], provided [T, T]

If you instead use the 'works' part instead, then you get a correctly-constructed object.

I don't know much about the internal workings of PODAM, but this seems like a bug to me. I would prefer to not have to modify my own business logic types (represented here as MyType). Is there a workaround?

Thanks,

Hi,

  I'm affraid there is no workaround, unless you tell Podam to skip filling of this field and then fill it yourself.
  Could you please report this issue on  https://github.com/devopsfolks/podam

Thanks for your reply.
