Setting targetElement param in @IndexedEmbedded on collection causes runtime exception
--------------------------------------------------------------------------------------

                 Key: HSEARCH-1111
                 URL: https://hibernate.onjira.com/browse/HSEARCH-1111
             Project: Hibernate Search
          Issue Type: Bug
          Components: mapping
    Affects Versions: 3.4.2
         Environment: Hibernate 3.6.10, mysql 5.1
            Reporter: Elmer van Chastelet
         Attachments: embeddedTestWithAdditionalTargetClassField.diff

When I have an @IndexedEmbedded field with the targetElement set to a subclass of the embedded type (at least the case for a collection), indexing goes wrong.

After seeing this behavior in my own app, I extended src/test/java/org/hibernate/search/test/embedded/AbstractProduct to have a pricingFeatures field:

{code:java}
   @ManyToMany(mappedBy="product", cascade=CascadeType.ALL) //just to make the test easier, cascade doesn't really make any business sense
   @IndexedEmbedded(targetElement=PricingFeature.class)
   private Set<ProductFeature> pricingFeatures = new HashSet<ProductFeature>();
{code}

Added PricingFeature class:

{code:java}
package org.hibernate.search.test.embedded;

import org.hibernate.search.annotations.Field;
import org.hibernate.search.annotations.Index;

public class PricingFeature extends ProductFeature {

    @Field(index= Index.UN_TOKENIZED)
    private String price;

    public String getPrice() {
        return price;
    }

    public void setPrice(String price) {
        this.price = price;
    }
}
{code}

The test itself {{org.hibernate.search.test.embedded.EmbeddedTest}} is untouched, and {{testEmbeddedToManyInSuperslass}} fails with the following exception:

{code}

testEmbeddedToManyInSuperslass(org.hibernate.search.test.embedded.EmbeddedTest)

This is probably also applicable for HSearch 4.1.0, but untested.
