If no match is found the value returned by BUILD_LOG_REGEX is empty, which makes the resulting emails difficult to read. It would be great if we could provide a suitable default value. An example is given below:

${BUILD_LOG_REGEX, regex="^
*

Application: (.*)$", maxMatches=1, showTruncatedLines=false, substText="$1", addNewline=false, noMatchText="UNKNOWN"}
