The parsing of the `javax.net.debug` system property for TLS/SSL debug logging has been updated to strictly enforce documented option and sub-option relationships. Sub-options such as `verbose`, `packet`, and `plaintext` now require their respective parent options, and only valid combinations have an effect. Invalid or unsupported combinations are silently ignored.

Previously, some sub-options could be used independently or in incorrect combinations, contrary to the intended design. The help message (`-Djavax.net.debug=help`) has also been updated to accurately reflect all supported and obsolete entries.

Users who previously relied on undocumented or invalid combinations (for example, specifying only `-Djavax.net.debug=verbose`) will need to update their configurations to match the documented usage. Please refer to the updated help output for the current list of valid options and examples of correct usage.
