Parece que realmente esse problema foi contorno na versao Spring BlazeDZ Integration 1.5, como é tido no texto:
Using Hibernate to handle persistence concerns is quite common in Spring applications. A common problem arises, though, when attempting to directly use Hibernate-loaded entities in AMF messages with BlazeDS. In essence, the default BlazeDS serialization mechanism tries to walk the entire object graph, forcing initialization of any lazily loaded associations that might be encountered. This generally leads either to LazyInitialization errors, or (if using a solution such as Spring's OpenSessionInViewFilter) the undesirable n+1 selects scenario. The other problem that arises is when associations are eagerly loaded, but still wrapped in a Hibernate-specific collection or proxy, which can cause unexpected results in the way the association gets serialized. Spring BlazeDS Integration 1.5+ provides a simple solution that will allow the direct use of Hibernate entities in AMF messages. A special Spring-aware PropertyProxy (a BlazeDS-specific interface for customizing serialization) is automatically installed that delegates to the Spring 3.0 ConversionService to allow for additional property conversion logic to be plugged in during the serialization/deserialization process. Como ainda estou usando a versao Spring BlazeDS Integration 1.0.3 não tive a oportunidade de testar essa nova versao do Integration...
