use new FstCodec(FSTConfiguration.createDefaultConfiguration(), false) as codec or try Kryo5Codec

use new FstCodec(FSTConfiguration.createDefaultConfiguration(), false) as codec or try Kryo5Codec Sorry, Wrong verification before. Use new FstCodec(FSTConfiguration.createDefaultConfiguration(), false) This problem did not reproduce. This problem did not reproduce,Thank you.
