    NullPointerException after JBoss 2.2.4 restarts

      Hi,
      we're using a hypersonic database combined with entity beans. Some of the beans contain Collections filled with objects or other Beans (instead of using primary keys - hoping this improves performance by reducing findBy's). When JBoss restarts, any method performed on a bean extracted from such a Collection, will result in: java.lang.NullPointerException at org.jboss.ejb.plugins.jrmp.interfaces.EntityProxy.invoke(EntityProxy.java:182) at $Proxy11.[method name](Unknown Source).
      Does this mean persistence is lost when you store objects?

      I would greatly appreciate detailed answers if anyone has a clue...
