Description

RegexFilter is constructed with a pattern, but pattern does not support multiline matches, so impossible for the filter to ever match a multiline msg.
Should maybe provide a multline="x attribute whichi should default to true and result in the patter being compiled as such:
Pattern pattern = Pattern.compile(".line.", Pattern.DOTALL);
