title: Note: Failed to read get kotlin metadata for [Ljava.lang.Object;@79d6c4df
body: <p>I keep getting this error. 
  I am working on a project and in the middle of development, I decided to migrate to Android X. </p>
  
  <p>I get the error below:</p>
  
  <pre><code>Note: Failed to read get kotlin metadata for [Ljava.lang.Object;@79d6c4df
  </code></pre>
  
  <p>There is the same error in a entity file and 4 of the same error in the respective DAO as well.</p>
  
  <p>Here is the code of DAO:</p>
  
  <pre><code>@Dao
  public interface FlockDao{
      @Query("SELECT * FROM flock_table")
      LiveData&lt;List&lt;Flock&gt;&gt; getAllFlocks();
  
      @Query("SELECT * FROM flock_table WHERE fid IN (:flockIds) LIMIT 1")
      Flock loadFlockById(int[] flockIds);
  
      @Insert
      void insert(Flock flock);
  
      @Update
      void update(Flock flock);
  
      @Delete
      void delete(Flock flock);
  }
  </code></pre>
  
  <p>And my entity is:</p>
  
  <pre><code>@Entity
  public class Flock{
  
      @PrimaryKey(autoGenerate = true)
      private int fid;
  
      @ColumnInfo(name = "user_id")
      private int uid;
  
      @ColumnInfo(name = "name")
      private String name;
  
      @ColumnInfo(name = "capacity")
      private int capacity;
  
      @ColumnInfo(name = "type")
      private String type;
  
      @ColumnInfo(name = "arrived")
      private Date arrived;
  
      .....rest of the code is omitted, there are constructor, setters and getters
  }
  </code></pre>
