           Summary: The insertion of a percent symbol causes the Parser to
                    crash
           Product: logback-core
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Pattern
        AssignedTo: logback-dev at qos.ch
        ReportedBy: noreply.sebastien at qos.ch


When inserting the percent char twice, so that it appears in the PatternLayout
output, a number format exception is thrown.

It does not prevent from using normally the PatternLayout.
