-----------------------------------------------

Solved this with embedded flag in regex: "(?s).*test.*" matches "test\n"

> 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);
> See attached UnitTest illustrating failure
