> Key: LOG4J2-696
> URL: https://issues.apache.org/jira/browse/LOG4J2-696
> Project: Log4j 2
> Issue Type: Bug
> Components: Filters
> Affects Versions: 2.0-rc2
> Reporter: phil wray
> Assignee: Ralph Goers
> Priority: Major
> Attachments: RegexFilterTest.java
>
>
> 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
