yjshen opened a new issue #4488: [Schema][AVRO] Unable to read fields of java built-in types defined in POJO class
URL: https://github.com/apache/pulsar/issues/4488
 
 
   **Describe the bug**
   `AvroSchema` and `GenericAvroSchema` cannot read POJO field's of java built-in types, `GenericAvroSchema` lose all java built-in fields' value when read, and `AvroSchema` will lose part of them,  `BitSet` for example.
   
   **To Reproduce**
   ``` java
   class Foo {
      boolean b;
      java.util.Date dt;
      java.util.BitSet bs;
   }
   
   Schema sa = Schema.AVRO(Foo.class);
   Schema sb = Schema.getSchema(a.getSchemaInfo());
   
   Consumer ca = client.newConsumer(a)....subscribe();
   Consumer cb = client.newConsumer(b)....subscribe();
   ```
   For `ca`, `dt` can be read, `bs` is empty
   For `cb`, both `dt` and `bs` is empty
