--------------------------------------
Summary: SyslogParser regex fails to handle messages that end
with Windows style new line
Key: NIFI-5703
URL: https://issues.apache.org/jira/browse/NIFI-5703
Project: Apache NiFi
Issue Type: Bug
Reporter: Joseph Percivall
The common SyslogParser class, which is used by ListenSyslog and ParseSyslog,
has two different regexes to match the RFCs for syslog. Both of which end in a
"(.*)$"[1]. There is also special handling if the last character is "\n"[2].
Note that "." does not match any of the newline characters[3].
The endline handling should be expanded to handle "\r\n".
