Michael Donaghy created BEANUTILS-415:
-----------------------------------------
Summary: Read method returned for a generic method overridden in a
subclass is inconsistent between java 1.6 and 1.7
Key: BEANUTILS-415
URL: https://issues.apache.org/jira/browse/BEANUTILS-415
Project: Commons BeanUtils
Issue Type: Bug
Components: Bean / Property Utils
Environment: Linux/maven
Reporter: Michael Donaghy
Priority: Minor
The test below passes when run under java 1.7, but fails under java 1.6. I feel
the behaviour should be consistent between the two. I will provide more details
if there is any difficulty reproducing.

public class PropertyUtilsTest {
public static class Superclass<S> {
private S property;
public S getProperty() {
return property;
}
}
public static class Subclass extends Superclass<String> {
@Override
public String getProperty() {
return super.getProperty();
}
}
@Test
public void usesSubclassAccessorMethod() throws Exception {
final PropertyDescriptor[] descriptors =
PropertyUtils.getPropertyDescriptors(PropertyUtilsTest.Subclass.class);
final PropertyDescriptor descriptor =
Iterables.find(Arrays.asList(descriptors), new Predicate<PropertyDescriptor>() {
@Override
public boolean apply(final PropertyDescriptor input) {
return "property".equals(input.getName());
}
});
assertThat(descriptor.getReadMethod()).isEqualTo(Subclass.class.getMethod("getProperty")).isNotEqualTo(Superclass.class.getMethod("getProperty"));
}
}
