How do I cure the cause of the occasional exception IllegalArgumentException occurred while calling setter that Hibernate throws when my program attempts to load a user by name from the database?
Am I incorrectly mapping column USER_RV in table User to class Integer instead of BigDecimal or some other integer type? Note that the same application maps NUMBER columns in other tables to Integer objects, but Hibernate does not throw this exception when populating an object with a row from those tables.
Further note that the program enables RMI cache replication for the User cache only. Might this exception be related to cache replication? Is it a bug in Ehcache or Hibernate?
