[GitHub] [flink] klion26 opened a new pull request #11614: [FLINK-16916][serialization] Fix the logic of NullableSerializer#copy

klion26 opened a new pull request #11614: [FLINK-16916][serialization] Fix the logic of NullableSerializer#copy
URL: https://github.com/apache/flink/pull/11614
 
 
   ## What is the purpose of the change
   
   Fix the wrong logic of `NullableSerializer#copy`, 
   currently, the logic is such as below:
   ```
   public void copy(DataInputView source, DataOutputView target) throws IOException {
      boolean isNull = source.readBoolean();
      target.writeBoolean(isNull);
      if (isNull) {
         target.write(padding);
      }
      else {
         originalSerializer.copy(source, target);
      }
   }
   ```
   we forgot to skip paddings.length bytes when if the padding's length is not 0.
   
   We can correct the logic such as below 
   ```
   public void copy(DataInputView source, DataOutputView target) throws IOException {
      boolean isNull = deserializeNull(source); // this will skip the padding values.
      target.writeBoolean(isNull);
      if (isNull) {
         target.write(padding);
      }
      else {
         originalSerializer.copy(source, target);
      }
   }
   ```
