We see the following errors / warnings when using jetty.sh with an older version of bash. expr: warning: unportable BRE: `^#': using `^' as the first character of the basic regular expression is not portable; it is being ignored expr: warning: unportable BRE: `^#': using `^' as the first character of the basic regular expression is not portable; it is being ignored expr: warning: unportable BRE: `^#': using `^' as the first character of the basic regular expression is not portable; it is being ignored Bash 3.1.17 Fedora Core 5 (x86 version)
The root cause is a flaw in the expr syntax to skip comments in the etc/jetty.conf file, not in the bash script syntax.
Fixed in trunk revision 1990
