             Summary: 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


When value in left-justified field is longer than maximum width following exception is thrown:
{code}
java.lang.StringIndexOutOfBoundsException

{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}
