1. Based on some further research, I did not find any "java.lang.Object" declaration in the (Beans/VO, Action forms, Decorators) of the application classes. 2. The Mappings are clean and theres no DB -> field mapping of type Object. 3. Although, In "com.ibatis.db.sqlmap.cache.memory" package, MemoryCacheController has a inner class declaration "StrongReference", which has java.lang.Object declaration.
