(7.1.0) StringIndexOutOfBoundsException throw while formatting log with truncation

XMLWordPrintable

      This is clone of https://issues.jboss.org/browse/LOGMGR-141

      When value in left-justified field is longer than maximum width following exception is thrown:

      java.lang.StringIndexOutOfBoundsException

      Steps to Reproduce:

      1. Configure formatter with left-justified field with maximum width:

      /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")

      (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:

      builder.delete(oldLen, overflow + 1);

      but should be:

      builder.delete(oldLen, oldLen + overflow);
