[jira] [Updated] (CASSANDRA-10946) jemalloc detection fails due to quoting issues in regex

["Bernhard K. Weisshuhn (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-10946?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bernhard K. Weisshuhn updated CASSANDRA-10946:
----------------------------------------------
    Description: 
When creating the list of paths where to search for jemalloc, we parse ldconfig output to get more directories. The current pattern used to filter out indented rows from ldconfig does not work because of quoting issues of the involved dollar sign.

I found just changing the regex to '^\s' works and seems less error prone.
