StackOverflow Exception for serializing off heap ByteBuffer by allocateDirect()

Demo as below:

  public static void main(String[] args) {
      ByteBuffer buf= ByteBuffer.allocateDirect(100);
      for(int i=1; i<=buf.capacity()/4; i++) {
          buf.putInt(i);
      }
      byte[] protostuffByte ;
      LinkedBuffer buffer = LinkedBuffer.allocate(LinkedBuffer.DEFAULT_BUFFER_SIZE);
      Class<ByteBuffer> clazz = (Class<ByteBuffer>) buf.getClass();
      try {
          Schema<ByteBuffer> schema = RuntimeSchema.getSchema(clazz);
          protostuffByte = ProtostuffIOUtil.toByteArray(buf, schema, buffer);
      } catch (Exception e) {
          throw new IllegalStateException(e.getMessage(), e);
      } finally {
          buffer.clear();
      }
  }

  1. Use a pojo that wraps the buffer.
  2. Register a delegate for the byte buffer.
