NotSerializableException when using clustered authentication cache ------------------------------------------------------------------ Key: SECURITY-984 URL: https://issues.jboss.org/browse/SECURITY-984 Project: PicketBox Issue Type: Bug Components: PicketBox Affects Versions: PicketBox_5_0_2.Final Reporter: Gert Kropiunik Assignee: Stefan Guilhen After migrating from wildfly 10 to wildfly 11 I have troubles using a distributed authentication cache. I get serialization errors in the JBossCachedAuthenticationManager$DomainInfo class. See forum link for whole discussion and stacktrace. From the exception it looks like that the DomainInfo object will be put into the cache although it has a member which is not serializable: protected ClassLoader contextClassLoader.
