Picocli 3.9.1

The picocli community is pleased to announce picocli 3.9.1.

The picocli.AutoComplete application no longer calls System.exit() unless requested by setting system property picocli.autocomplete.systemExitOnError or picocli.autocomplete.systemExitOnSuccess to any value other than false. Applications that rely on the exit codes introduced in picocli 3.9.0 need to set these system properties.

This release adds support for quoted map keys with embedded '=' characters.

This release contains bugfixes and enhancements.

This is the forty-sixth public release.
Picocli follows semantic versioning.

Potential breaking changes

The picocli.AutoComplete application no longer calls System.exit() unless requested by setting system property picocli.autocomplete.systemExitOnError or picocli.autocomplete.systemExitOnSuccess to any value other than false.
Applications that rely on the exit codes introduced in picocli 3.9.0 need to set these system properties.

The new support for quoted map keys with embedded '=' characters [#594] may inpact some existing applications.
If CommandLine::setTrimQuotes() is set to true, quotes are now removed from map keys and map values. This did not use to be the case.

For example:

class App {
    @Option(names = "-p") Map<String, String> map;
}

When CommandLine::setTrimQuotes() was set to true, given input like the below:

-p AppOptions="-Da=b -Dx=y"

The above used to result in a map with key AppOptions and value "-Da=b -Dx=y" (including the quotes), but the same program and input now results in a map with key AppOptions and value -Da=b -Dx=y (without quotes).

Also, when CommandLine::setTrimQuotes() is false (the default), input like the below will now cause a ParameterException ("value should be in KEY=VALUE format"):

-p "AppOptions=-Da=b -Dx=y"

Prior to this release, the above was silently ignored (no errors but also no key-value pairs in the resulting map).
