> LOG4J2-1274 added the {{encode(LogEvent, ByteBufferDestination)}} method to Layout. The default implementation in AbstractLayout calls the existing {{toByteArray}} logic and writes the result into the ByteBuffer, so all layouts work as before even when the new method is called.
> This ticket is to modify PatternLayout to utilize the {{TextEncoderHelper}} class to avoid creating temporary objects when the {{encode}} method is called.
