Description

When I try to add the default property converters to the ConfigurationContextBuilder like

ConfigurationContextBuilder builder = ConfigurationProvider.getConfigurationContextBuilder();
builder.addDefaultPropertyConverters();

I get the following error

Checking the EnumConverter this makes sense because of missing default constructor but I can't see how it has been added because it is not a part of the core converters.
