Map<String, Instant> return type is missing model

[MichaelZett]

After upgrading to Version 3.0.0 (from 2.9.2) a return type of Map<String, Instant> leads to following error message:

"Unable to find a model that matches key ModelKey{qualifiedModelName=ModelName{namespace='java.time', name='Instant'}, viewDiscriminator=null, validationGroupDiscriminators=[], isResponse=true}"

and the model for the return type is not generated but:
"

< * >:	{...}
"

I was able to work around this with:
.alternateTypeRules(
new AlternateTypeRule(
typeResolver.resolve(Map.class, String.class, Instant.class),
typeResolver.resolve(Map.class, String.class, Date.class)
)
)

Thanks for reporting!

I think return types based on Maps are the problem. Another one I found was Map<String,MonetaryAmount>.
We have a ".directModelSubstitute(MonetaryAmount.class, MoneyNode.class)" for this, that does not work with Map-based return types. Adding
new AlternateTypeRule(
typeResolver.resolve(Map.class, String.class, MonetaryAmount.class),
typeResolver.resolve(Map.class, String.class, MoneyNode.class)
)
like above solves the problem.

Type substitutions need to be explicit, but let me see if I can address this
