shibd opened a new pull request, #15235:
URL: https://github.com/apache/pulsar/pull/15235

   ### Motivation
   
   https://github.com/apache/pulsar/issues/15091
   
   The essential reason for https://github.com/apache/pulsar/pull/13911 is that 
two threads execute the refresh method concurrently. In PR 
https://github.com/apache/pulsar/pull/13911 change, it doesn't completely solve 
the problem, just avoid concurrent access by threads.
   
   In #14283, The problem was radically resolved by changing below.
   ```
   objCache.asMap().computeIfPresent(path, (oldKey, oldValue) -> 
readValueFromStore(path));
   ```
   So, revert this commit.
