> Components: API

> Reporter: Gary D. Gregory
> Priority: Major
> Fix For: 2.18.0

> 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 updated 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}
> Options:
> - Don't log the exception (simple)
> - Log at the TRACE level instead of ERROR.
> - Provide a better simpler localized MessageFactory that does not perform % substitution
> - ?
> I read the Javadoc that says that using a localized MessageFactory is not preferred, but it would be a large change for our app.
