@datalorax Commons Lang has been migrated from svn to git. Because of this
the main branch has been renamed to 'master'. Can you please rebase your work
against the master branch? Thank you!
> TypeUtils.ParameterizedType#equals doesn't work with wildcard types

> Key: LANG-1114
> URL: https://issues.apache.org/jira/browse/LANG-1114
> Project: Commons Lang
> Issue Type: Bug
> Components: lang.reflect.*
> Affects Versions: 3.3.2, 3.4
> Reporter: andrew coates
> Assignee: Benedikt Ritter
> Fix For: Review Patch
>
>
> There is a bug in TypeUtils.equals(WilcardType, Type). It returns true if
> the other type is not a WildcardType, it should return false. See
> TypeUtils@1629 for v3.3.2 and TypeUtils@791 for v3.4
> Bug can be seen with the following test:
> {code}
> @Test
> public void shouldHandleEqualityOfParameterizedTypesWithWildcards()
> throws Exception {
> // Given:
> class SomeType {
> Collection<?> field;
> }
> final ParameterizedType wildcardCollectionType = (ParameterizedType)
> SomeType.class.getDeclaredField("field").getGenericType();
> final WildcardType wildcard = (WildcardType)
> wildcardCollectionType.getActualTypeArguments()[0];
> final ParameterizedType ptWithWildcard =
> TypeUtils.parameterize(Collection.class, wildcard);
> final ParameterizedType otherPt =
> TypeUtils.parameterize(Collection.class, String.class);
> // Then:
> assertThat(otherPt, is(not(equalTo(ptWithWildcard)))); // Passes
> assertThat(ptWithWildcard, is(not(equalTo(otherPt)))); // Fails
> }
> {code}
