Description

When the metadata file looks like
<?xml version="1.0" encoding="utf-8"?>
<edmx:Edmx Version="4.0" xmlns:edmx="http://docs.oasis-open.org/odata/ns/edmx">
<edmx:DataServices>
<Schema Namespace="caps.products.CatalogService" Alias="caps.products.CatalogService" xmlns="http://docs.oasis-open.org/odata/ns/edm">
<Annotations Target="caps.products.CatalogService.Products">
<Annotation Term="UI.LineItem">
<Collection>
<Record Type="UI.DataField">
<PropertyValue Property="Value" Path="image"/>
<Annotation Term="UI.Importance" EnumMember="UI.ImportanceType/High" />
</Record>
</Collection>
</Annotation>
</Annotations>
</Schema>
</edmx:DataServices>
</edmx:Edmx>
The jackson parser parses the entire document correctly. All artifacts of edmx object are seen properly but doesn't exit the program. This is happening because the JsonToken is null and this does not indicate the end object.
This can be solved by using the method hasCurrentToken(). If currentToken is null this evaluates to false.
