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$FormatSpecifier.conversion(Formatter.java:2691) at java.util.Formatter$FormatSpecifier.<init>(Formatter.java:2720) at java.util.Formatter.parse(Formatter.java:2560) at java.util.Formatter.format(Formatter.java:2501) at java.util.Formatter.format(Formatter.java:2455) at java.lang.String.format(String.java:2981) at org.apache.logging.log4j.message.StringFormattedMessage.formatMessage(StringFormattedMessage.java:116) at org.apache.logging.log4j.message.StringFormattedMessage.getFormattedMessage(StringFormattedMessage.java:88) at org.apache.logging.log4j.message.FormattedMessage.getFormattedMessage(FormattedMessage.java:178) at org.apache.logging.log4j.message.LocalizedMessage.getFormattedMessage(LocalizedMessage.java:196) at org.apache.logging.log4j.message.LocalizedSimpleMessageFactoryTest.testNoMatchPercentInMessage(LocalizedSimpleMessageFactoryTest.java:79) 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} -- This message was sent by Atlassian Jira (v8.20.1#820001)
