TypeUtils.getTypeArguments() misses type arguments for partially-assigned
classes
---------------------------------------------------------------------------------
Key: LANG-775
URL: https://issues.apache.org/jira/browse/LANG-775
Project: Commons Lang
Issue Type: Bug
Components: lang.reflect.*
Affects Versions: 3.1
Reporter: Matt Benson
Assignee: Matt Benson
failing test code to add to TypeUtilsTest.testGetTypeArguments():
{code}
typeVarAssigns = TypeUtils.getTypeArguments(Other.class, This.class);
Assert.assertEquals(2, typeVarAssigns.size());
Assert.assertEquals(String.class,
typeVarAssigns.get(This.class.getTypeParameters()[0]));
Assert.assertEquals(Other.class.getTypeParameters()[0],
typeVarAssigns.get(This.class.getTypeParameters()[1]));
{code}
These should pass based on:
{code}
public interface This<K, V> {
}
public class Other<T> implements This<String, T> {
}
{code}
This case fails because the current code ignores the Other class due to its
specifying its own type variables, which is obviously incorrect. This report
is extrapolated from an offline report received by Hen.
