[jboss-jira] [JBoss JIRA] Resolved: (JBLOGGING-63) Hexadecimal in log message error

Hexadecimal in log message error -------------------------------- Key: JBLOGGING-63 URL: https://issues.jboss.org/browse/JBLOGGING-63 Project: JBoss Logging Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 3.0.0.Beta5-jboss-logging Reporter: Galder Zamarreño Assignee: David Lloyd The following code fails with JBoss Logging: String message = "Invalid magic number. Expected %#x and received %#x"; log.invalidMagicNumber(message, HotRodConstants.RESPONSE_MAGIC, magic); With: java.util.IllegalFormatConversionException: x != java.lang.String at java.util.Formatter$FormatSpecifier.failConversion(Formatter.java:3999) at java.util.Formatter$FormatSpecifier.printInteger(Formatter.java:2709) at java.util.Formatter$FormatSpecifier.print(Formatter.java:2661) at java.util.Formatter.format(Formatter.java:2433) at java.util.Formatter.format(Formatter.java:2367) at java.lang.String.format(String.java:2769) at org.jboss.logging.Log4jLogger.doLogf(Log4jLogger.java:48) at org.jboss.logging.Logger.logf(Logger.java:2130) at org.infinispan.client.hotrod.logging.Log_$logger.invalidMagicNumber(Log_$logger.java:820) at org.infinispan.client.hotrod.impl.operations.HotRodOperation.readHeaderAndValidate(HotRodOperation.java:106) at org.infinispan.client.hotrod.impl.operations.AbstractKeyValueOperation.sendPutOperation(AbstractKeyValueOperation.java:70) at org.infinispan.client.hotrod.impl.operations.PutOperation.executeOperation(PutOperation.java:49) at org.infinispan.client.hotrod.impl.operations.RetryOnFailureOperation.execute(RetryOnFailureOperation.java:62) at org.infinispan.client.hotrod.impl.RemoteCacheImpl.put(RemoteCacheImpl.java:201) at org.infinispan.CacheSupport.put(CacheSupport.java:51) at org.infinispan.client.hotrod.ServerErrorTest.testErrorWhileDoingPut(ServerErrorTest.java:87) Whereas the following works: log.info(String.format("Invalid magic number. Expected %#x and received %#x", HotRodConstants.RESPONSE_MAGIC, magic)); And prints: 2011-05-18 14:58:43,929 INFO [HotRodOperation] (main) Invalid magic number. Expected 0xa1 and received 0xa1 It seems like JBoss Logging is doing something that avoids hexadecimals to be shown in the same way as you'd do with String.format(). Maybe JBoss Logging is expecting something different here?
