[via GitHub]

URL: https://github.com/apache/lucene/pull/14920

   `IndexFileNames.parseGeneration` allocates multiple unnecessary strings (3-6 
strings per call) + string[] objects:

   With often reindexing this allocations become notable during profiling. 
These allocations could be easily eliminated with a manual underscore search. 
After the fix only 1 string will be allocated in the worst case.
