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

             Summary: LocalizedMessage causes a lot of noise on the console
                 Key: LOG4J2-3458
                 URL: https://issues.apache.org/jira/browse/LOG4J2-3458
             Project: Log4j 2
          Issue Type: Bug
          Components: API
    Affects Versions: 2.17.2
            Reporter: Gary D. Gregory


I have an app where we log data that is percent encoded through a localized 
message factory. We get a ton of noise on the console due to logging of 
internal exceptions, for example:

ERROR StatusLogger Unable to format msg: 
C:/Program%20Files/Some%20Company/Some%20Product%20Name/
 java.util.UnknownFormatConversionException: Conversion = 'F'
    at java.util.Formatter$FormatSpecifier.conversion(Formatter.java:2691)

I added to this test to demonstrate: 
[https://github.com/apache/logging-log4j2/blob/release-2.x/log4j-api/src/test/java/org/apache/logging/log4j/message/LocalizedMessageFactoryTest.java]

In a nutshell:
{code:java}
    @Test
    public void testNoMatchPercentInMessage() {
        final LocalizedMessageFactory localizedMessageFactory = new 
LocalizedMessageFactory(ResourceBundle.getBundle("MF", Locale.US));
        final Message message = 
localizedMessageFactory.newMessage("C:/Program%20Files/Some%20Company/Some%20Product%20Name/");
        
assertEquals("C:/Program%20Files/Some%20Company/Some%20Product%20Name/", 
message.getFormattedMessage());
    }
{code}
