Do you work on this issue?
My expected result:
{color:#660e7a}log{color}.warn({color:#008000}"test{color}{color:#000080}\n{color}{color:#008000}"{color});
<{color:#000080}RegexFilter {color}{color:#0000ff}regex{color}{color:#008000}=".*{color}{color:#008000}*test.**" {color}{color:#0000ff}onMatch{color}{color:#008000}="DENY" {color}{color:#0000ff}onMismatch{color}{color:#008000}="ACCEPT"{color}/>
should not log "test". But it is logging test.
Without the \n the RegexFilter is working.

> 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
