             Summary: StringIndexOutOfBoundsException in exceptionFormatStep
                 Key: LOGMGR-42
                 URL: https://issues.jboss.org/browse/LOGMGR-42
             Project: JBoss Log Manager
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: core
    Affects Versions: 1.3.1.Final
            Reporter: Marcus Klimstra
            Assignee: David Lloyd


StringIndexOutOfBoundsException is thrown when the path does not contain a jarName.
In my case path is "/com/.../Foo.class" (from a custom classloader). 

Stacktrace:

java.util.logging.ErrorManager: 5: Formatting error
java.lang.StringIndexOutOfBoundsException: String index out of range: -1
	at java.lang.String.charAt(String.java:686)
	at org.jboss.logmanager.formatters.Formatters$12.renderExtended(Formatters.java:524)
	at org.jboss.logmanager.formatters.Formatters$12.renderRaw(Formatters.java:388)

	at org.jboss.logmanager.Logger.logRaw(Logger.java:721)
	at org.jboss.logmanager.Logger.log(Logger.java:539)

The exception occurs here: (last line with while)

if (jarName == null) {
	// OK, that would have been too easy.  Next let's just grab the last piece before the class name
	int endIdx = path.lastIndexOf(classResourceName);
	if (endIdx != -1) {
		do {
			endIdx--;
		} while (path.charAt(endIdx) == '/' || path.charAt(endIdx) == '\\' || path.charAt(endIdx) == '?');

Since there is nothing before the initial /, endIdx becomes -1.
