Test, validate and match regular expressions
This regex matches Java-style log entries with a timestamp (date-time with milliseconds), logger/thread information, a log level, and message content. It's commonly used to parse log files from Java applications using frameworks like Log4j or SLF4J, where each line follows a structured format with timestamp, class name, log level, and message details.
