    Hello, i'm using spring-data release-train {{Gosling-RC1}} and hibernate5. I have a set of JPA repositories exposed via REST, and I'm issuing the following {{PATCH}} request: {code} http://localhost:8111/storefront/rest/blog_entry/197034105302123248 {code} with {{Content-Type: application/json-patch+json}} and body: {code} [ {"op": "add", "path": "/categories", "value": ["http://localhost:8111/storefront/rest/blog_category/197034105302120976"] } ] {code} It works fine for primitive properties when the {{op}} is replace. But now I try to add a category to the {{Collection}} of categories and I get this exception: {code} 2015-08-26 00:25:43,733

    java.lang.ClassCastException: java.util.LinkedHashSet cannot be cast to org.hibernate.collection.spi.PersistentCollection
  3. 0

    I believe HHH-9615 is not done. The test case there converts String to Integer, to represent it as Lob, but these are both basic regular types. If instead of a String you use something else (some custom Class), it doesn't seem to work. For example, here I use a class called Imagem, and convert it to a String: {code:java} @Converter public class ImagemToString_Converter implements AttributeConverter<Imagem, String> { public String convertToDatabaseColumn(@Nullable Imagem attribute) { if (attribute== null) return null; return attribute.toString(); } public Imagem convertToEntityAttribute(@Nullable String dbData) { return Imagem.getInstance(dbData); } } {code} The above code works OK as long as the field is not a @Lob (which means the converter itself is correct). But as soon as I add @Lob to the field it stops working. For example: {code:java} @Lob protected Imagem fotografia; {code} Then, when I try to save, it should see a String (the converter gets called), but it still sees an Imagem, and then I get this:
