Description

Describe the bug Am creating a pulsar window function with max message retry property using java runtime the expectation is to not allow to create window function. but it is creating the function.

To Reproduce Steps to reproduce the behavior:

  1. Create a window function with max message retry property
  2. window function created

Expected behavior Window function should handle exception when we provide max-message-retry for creating the window function

Pulsar version :2.7.0

Additional context By default auto-ack is false for window function so when we provide max-message-retry it should handle exception

Contributor guide

Research direction
Investigate the validation logic when creating a window function. Locate the code path that handles the maxMessageRetries parameter and determine why it does not reject the creation for window functions. Look for existing validation for non window functions and adapt it.
