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

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 be 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 pack 8.5.0.2.  Please refer to the Recommended
Updates page for delivery information:
