baynes opened a new issue #7168:
URL: https://github.com/apache/pulsar/issues/7168
**Describe the bug**
If a new topic is added that matches a regex subscription then if the client
is written in Java it detects it and adds a cursor but if it is written in
Python it does not.
**To Reproduce**
Steps to reproduce the behavior:
Run the following as a Phython3 client:
```
#!/usr/bin/python3
import pulsar
import re
client = pulsar.Client("pulsar://localhost:6650")
initial_position=pulsar.InitialPosition.Earliest )
consumer = client.subscribe(re.compile('.*'), subscription_name='my-sub' )
while True:
msg = consumer.receive()
print("Received message '%s'" % msg.data())
consumer.acknowledge(msg)
client.close()
```
In another window run this command to get a Java client for comparison:
```
/opt/pulsar/bin/pulsar-client consume --regex '.*' -s all -n 0
```
In another window send a message to a new topic:
```
/opt/pulsar//bin/pulsar-client produce addtopic -m 'm1'
```
Wait a minute for the clients to detect the new topic.
Send another message to the same topic.
```
/opt/pulsar//bin/pulsar-client produce addtopic -m 'm2'
```
The Java client receives the message but the Python one does not.
Kill and restart the clients. Send a message to the same topic.
```
/opt/pulsar//bin/pulsar-client produce addtopic -m 'm3'
```
Both clients receive the message.
**Expected behavior**
Both clients should receive the second message.
**Screenshots**

**Desktop (please complete the following information):**
