@Plugin(name="SafeExtendedThrowablePatternConverter",
        category="Converter",
        elementType="converter",
        printObject=true)
public final class SafeExtendedThrowablePatternConverter
extends org.apache.logging.log4j.core.pattern.ThrowablePatternConverter

Outputs the Throwable portion of the LoggingEvent as a full stack trace unless this converter's option is 'short', where it just outputs the first line of the trace, or if the number of lines to print is explicitly specified.

The extended stack trace will also include the location of where the class was loaded from and the version of the jar if available.

If the message of the throwable contains a carriage return or line feed character, it gets encoded to prevent log injection. Originally written by Benjamin Papez (Jahia) benjamin.papez@jahia.com Contributed to Apache Unomi by Jahia Solutions Group SA
