When I try to populate JbossCache I get this exception .
I try to put in the cache a collection of the object MessageWrapper which
contain a field of the object AddMessageData.
And it occures ones in a while .
what could be the reason for that ?
org.jboss.util.NestedRuntimeException: cannot assign instance of
com.comverse.ppg.common.data.AddMessageData to field
com.comverse.dal.message.MessageWrapper.wrapedObject of type
com.comverse.ppg.common.data.MessageData in instance of
com.comverse.dal.message.MessageWrapper; - nested throwable:
