The attempt to save an updated java.util.LinkedList as a BLOB via CMP EntityBean goes wrong in some cases. If the List added a new element or removed an element, the changed List is persisted as BLOB via CMP. In this case the CMP works correctly.
But if an attribute of one element in the List changed, the changed List will not be persited. It seems that only the size of an List decided, if the BLOB with the List will be updated by the Container or not. Is it so?
