Wrong type Exception when changing the order of @JsonSubTypes annotation

Thank you for the excellent library. Unfortunately I am having some trouble when using a more complex structure. Here is a minimal Example:

Given the following hierarchy:

@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, property = "type")
@JsonSubTypes({
		@JsonSubTypes.Type(Line.class),
		@JsonSubTypes.Type(Pt.class) })
public static class Loc  {
}

@JsonSubTypes({
		@JsonSubTypes.Type(Abs.class)
})
public static class Pt extends Loc {
}
public static class Abs extends Pt {
}

public static class Line extends Loc {
	public List<Pt>attr;
}

the generator throws the exception Wrong type - working on [simple type, class com.example.Pt] - got [simple type, class com.example.Abs] when calling ‘generator.generateJsonSchema(Loc.class);’

When changing the order of the subtype annotation on Loc to

@JsonSubTypes({
		@JsonSubTypes.Type(Pt.class),
		@JsonSubTypes.Type(Line.class) })

everything works. Unfortunately in our POJOs we cannot modify all of subtype annotations to ensure that there is no backward dependency between them. Is this something that is easy to fix?

I have the same issue.

Is my PR #109 not sufficient? I am sorry, I tried to mimic the style of the other tests, but I am not sure how it is supposed to work,
