Default value for PropertyType.PROPERTY_SET with multiple fields

I would like to set a default value for a property with type PropertyType.PROPERTY_SET and multiple fields. How do i accomplish that? The default value field is only a String.

        .description("List of known licenses with allowed status")
                .description("The name of the license (e.g. GNU General Public License v3.0 only).")
                .description("If the license is allowed to use")
        .defaultValue("") // <-- what to write here?

Hello Christian,

defaultValue is not supported for multiple fields Properties. You need to remove the line .defaultValue(""), as "" is interpreted as null, and a null default value is not allowed.
