   @zrlw Thanks for the suggestion! I've added a test case with 
`NarrowNumberPojo` that has `byte age`, `short height`, `float salary` fields, 
plus `List<Byte> scores` and `Map<String, Byte> attributes` fields.
   
   The test (`testReadObjectWithGenericType_pojoWithNarrowNumberFields`) 
verifies that:
   - Primitive narrow number fields (`byte`, `short`, `float`) are deserialized 
correctly
   - `List<Byte>` and `Map<String, Byte>` fields inside the POJO are also 
deserialized correctly
   - The fix does not affect POJO deserialization in any way
   
   This is expected because when the method parameter is a POJO (e.g., 
`processPerson(Person person)`), `genericParameterTypes[i]` equals `pts[i]` 
(both are `Person.class`), so the code falls through to the original 
`readObject(Class)` path — POJO fields are handled by hessian2's 
`JavaDeserializer` which already reads field type info from the class 
definition.
   
   All 16 tests pass locally.
