> When attempting to put a WorkingMemory that contains rules relying on activation groups into a TreeCache (which passivates with a JDBC connection), the following happens:
> 16:55:00,925 ERROR [JDBCCacheLoader] Failed to insert node: org.drools.common.ActivationGroupImpl
> java.io.NotSerializableException: org.drools.common.ActivationGroupImpl
> ...
> Surely enough, checking the javadoc (4.0 included) shows that indeed ActivationGroupImpl is not serializable.
> And strangely its "cousin" AgendaGroupImpl is serializable.
> Any particular reason why ActivationGroupImpl is not serializable?
> It prevents us from caching our working memories, we'll have to passivate the rule bases instead, which has a big performance impact on our rule-heavy system. I hope there's an easy fix to that.
> In the meantime, I'll try to simply modify the source code to add "implements Serializable" to that class and see what happens. I'll add findings here.
