[rajputa-deshaw]

Describe the bug
The order of results when sorted by path is not correct. The results are not sorted alphabetically by path. Below is a screenshot of the results.

JDK: openjdk 17.0.6 2023-01-17
OS: Red Hat Enterprise Linux release 8.10 (Ootpa)

The order of results when sorted by path should be:

2. /infra:base/src/perl/...
3. /infra:base/src/python/...
