Picocli 4.3.1

The picocli community is slightly embarrassed to announce picocli 4.3.1. :-)

This release fixes some critical bugs:

• an IllegalArgumentException: wrong number of arguments was thrown when the @Option(scope = INHERIT) feature is used in a command that has subcommands defined in @Command-annotated methods
• a NullPointerException was thrown in DefaultParamLabelRenderer.renderParameterLabel for programmatically built models that have a non-null split regex and do not have a splitSynopsisLabel
• removed a call to the String.isEmpty method, which prevented picocli from running on Java 5: this method was introduced in Java 6

See Fixed issues for the full list of changes.

This is the sixty-nineth public release.
Picocli follows semantic versioning.
