Using plugin as "Update JIRA issues", DIscover Issues by "Mentioned somewhere in commit message"

Plugin seems to fail to extract JIRA ticket in certain conditions, like example shown below
where Commit message contains "Message...ticket#..3 spaces"

If I add \n to the end - jira plugin parses the commit line fine and extracts JIRA ticket fine

Commit string in GIT (shown in single quotes):
_____________________________
'Testing JIRA (ticket with a few spaces at the end and no EOL) SBUSWIT-141 '

Jenkins output (fails to show JIRA ticket SBUSWIT-141 and ticket is not updated)
