Findbugs reports the following error: >>> Bug: org.apache.commons.digester.annotations.utils.InMemoryLRUCache$1 is serializable but also an inner class of a non-serializable class Pattern id: SE_BAD_FIELD_INNER_CLASS, type: Se, category: BAD_PRACTICE
This Serializable class is an inner class of a non-serializable class. Thus, attempts to serialize it will also attempt to associate instance of the outer class with which it is associated, leading to a runtime error. If possible, making the inner class a static inner class should solve the problem. Making the outer class serializable might also work, but that would mean serializing an instance of the inner class would always also serialize the instance of the outer class, which it often not what you really want. <<< It's not possible to make the inner class static, however it should be possible to make the container Serializable. I'm not sure if that is wanted or not. If not, then I think the only solution is to document the fact that although the inner class is serializable, this is not intentional. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org For additional commands, e-mail: dev-h...@commons.apache.org
