Updating to Jackson 2.7+ Fails #4073
Description
Using Jackson 2.7+ with Spring Security's Jackson Support fails when trying to deserialize authorities. For example, after updating to Jackson 2.8.3 and adding the following added to SimpleGratnedAuthorityMixinTests
@Test
@SuppressWarnings("unchecked")
public void deserializeGrantedAuthoritiesTest() throws IOException {
Set<GrantedAuthority> authorities = mapper.readValue(AUTHORITIES_SET_JSON, Set.class);
assertThat(authorities).isNotNull();
assertThat(authorities).extracting("authority").containsOnly("ROLE_USER");
}fails with the following:
java.lang.IllegalStateException: No default constructor for [collection type; class java.util.Collections$UnmodifiableSet, contains [simple type, class java.lang.Object]]
