jimmycxm opened a new issue #12328:
URL: https://github.com/apache/pulsar/issues/12328


   **Describe the bug**
   Java client can subscribe persistent topics via regex, but failed to 
subscribe non-persistent topics.
   After some efforts, I found client  calls 
"/admin/v2/namespaces/{namespaces}/topics?mode=ALL" which can't return 
non-persistent topics.
   
   **To Reproduce**
   Steps to reproduce the behavior:
   1. Create topics like below:
   bin/pulsar-admin topics create 
non-persistent://goldwind/iothub/prop_data-BZ-FAST-1min-001
   bin/pulsar-admin topics create 
non-persistent://goldwind/iothub/prop_data-BZ-FAST-1min-002
   bin/pulsar-admin topics create 
non-persistent://goldwind/iothub/prop_data-BZ-FAST_Metric-1min-001
   bin/pulsar-admin topics create 
non-persistent://goldwind/iothub/prop_data-BZ-FAST_Metric-1min-002
   bin/pulsar-admin topics create 
persistent://goldwind/iothub/prop_data-BZ-GRID-1min-001
   bin/pulsar-admin topics create 
persistent://goldwind/iothub/prop_data-BZ-GRID-1min-002
   bin/pulsar-admin topics create 
persistent://goldwind/iothub/prop_data-BZ-GRID_SECTION-1min-001
   bin/pulsar-admin topics create 
persistent://goldwind/iothub/prop_data-BZ-GRID_SECTION-1min-002
   2. consumer subscribe to  
    
Pattern.compile("non-persistent://goldwind/iothub/prop_data-(BZ|IT|MK)-FAST-.*")
   3. No topic is subscribed.
   
   **Expected behavior**
   topic below should be matched:
   non-persistent://goldwind/iothub/prop_data-BZ-FAST-1min-001
   non-persistent://goldwind/iothub/prop_data-BZ-FAST-1min-002
   non-persistent://goldwind/iothub/prop_data-BZ-FAST_Metric-1min-001
   non-persistent://goldwind/iothub/prop_data-BZ-FAST_Metric-1min-002
   
   **Screenshots**
   Here're the topics.

   And no non-persistent topics are returned when calling 
"admin/v2/namespaces/{namespace}topics?mode=NON_PERSISTENT"
