    While a JAX-RS client reading response using JSON
    representation, an invalid UTF-8 middle byte error might occur
    during parsing some UTF-8 characters.
    The error is like the following:

    This error indicates that JAX-RS engine could not recognize
    the UTF-8 character which might already be corrupt.
    

Problem conclusion

  • While JAX-RS runtime is parsing content encoded in UTF-8, it
    will read the content into a String and then convert the String
    into a byte array after parsing. During this, some UTF-8
    characters might corrupted due to incorrect conversion.
    
    The JAX-RS runtime has been updated to correctly parse UTF-8
    characters.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 8.0.0.6 and 8.5.0.1.  Please refer to the Recommended
