Nested quantifiers in regex; marked by <-- HERE in m/^/InternalSystems/Documentation/Architecture/Infrastructure/New Notepad++ <-- HERE Document.txt.+/ at /usr/lib/perl5/site_perl/5.8.8/Atlassian/Crowd.pm line 448.\n
Cause

Resolution
You can work around the problem by editing the /usr/lib/perl5/site_perl/5.8.8/Atlassian/Crowd.pm file and replacing

if($path =~ /^$repos_path.+/) {
on line 448 with

if($path =~ /^\Q$repos_path\E.+/) {
You will need to restart Apache after making this change.
