StringIndexOutOfBoundsException throw while formatting log with truncation -------------------------------------------------------------------------- Key: LOGMGR-141 URL: https://issues.jboss.org/browse/LOGMGR-141 Project: JBoss Log Manager Issue Type: Bug Reporter: James Perkins Assignee: James Perkins Fix For: 1.5.7.Final, 2.0.5.Final, 2.1.0.Beta1 When value in left-justified field is longer than maximum width following exception is thrown: {code} java.lang.StringIndexOutOfBoundsException at java.lang.AbstractStringBuilder.delete(AbstractStringBuilder.java:733) at java.lang.StringBuilder.delete(StringBuilder.java:244) at org.jboss.logmanager.formatters.Formatters$JustifyingFormatStep.render(Formatters.java:212) at org.jboss.logmanager.formatters.MultistepFormatter.format(MultistepFormatter.java:83) at org.jboss.logmanager.ExtFormatter.format(ExtFormatter.java:32) at org.jboss.logmanager.handlers.WriterHandler.doPublish(WriterHandler.java:46) at org.jboss.logmanager.ExtHandler.publish(ExtHandler.java:76) at org.jboss.logmanager.LoggerNode.publish(LoggerNode.java:302) at org.jboss.logmanager.LoggerNode.publish(LoggerNode.java:310) at org.jboss.logmanager.LoggerNode.publish(LoggerNode.java:310) at org.jboss.logmanager.LoggerNode.publish(LoggerNode.java:310) at org.jboss.logmanager.Logger.logRaw(Logger.java:719) at org.jboss.logmanager.Logger.log(Logger.java:670) at org.jboss.logging.JBossLogManagerLogger.doLogf(JBossLogManagerLogger.java:50) at org.jboss.logging.Logger.logf(Logger.java:2096) {code} Steps to Reproduce: 1. Configure formatter with left-justified field with maximum width: {code} /subsystem=logging/periodic-rotating-file-handler=FILE:write-attribute(name=formatter,value="%d{HH:mm:ss,SSS} %-5p [%c{1.}] [%-20.-20t] %s%E%n") {code} (in the example above thread name should be truncated to 20 characters, left-justified) 2. Write a log from a thread which has a name containg 21 characters or more. During server startup logs are written by "MSC service thread 1-7" thread. It seems there is an error in {{org.jboss.logmanager.formatters.Formatters()}} class, line 212. There is: {code:java} builder.delete(oldLen, overflow + 1); {code} but should be: {code:java} builder.delete(oldLen, oldLen + overflow); {code}
