NPE in BeanReferenceCollectionConverterImpl on update on empty collection
-------------------------------------------------------------------------

                 Key: JCR-1470
                 URL: https://issues.apache.org/jira/browse/JCR-1470
             Project: Jackrabbit
          Issue Type: Bug
          Components: observation
    Affects Versions: 1.5
         Environment: mac os leopard, java5
            Reporter: Stephane Landelle


use case :
in the same transaction :
*) retrieve an object that has a collection of references, yet empty
*) add an element in the collection
*) update the object

consequence :
org.apache.jackrabbit.ocm.exception.ObjectContentManagerException: Cannot insert collection field : authors of class com.weka.content.api.model.Folder; nested exception is java.lang.NullPointerException: null
java.lang.NullPointerException
	at org.apache.jackrabbit.ocm.manager.collectionconverter.impl.ManageableArrayList$$EnhancerByCGLIB$$8f15dde4.getSize(<generated>)
	at org.apache.jackrabbit.ocm.manager.collectionconverter.impl.BeanReferenceCollectionConverterImpl.addUuidProperties(BeanReferenceCollectionConverterImpl.java:154)
	at org.apache.jackrabbit.ocm.manager.collectionconverter.impl.BeanReferenceCollectionConverterImpl.doUpdateCollection(BeanReferenceCollectionConverterImpl.java:101)

The failing line is in addUuidProperties :
Value[] values = new Value[collection.getSize()];

It seems the CGlib enhanced collection fails and needs to be initialized before.

For example, in doUpdateCollection, if I code :
		// Delete existing values
		if (parentNode.hasProperty(jcrName)) {
			parentNode.setProperty(jcrName, (Value[]) null);
		}
		
		if (collection != null) {
			collection.getSize();         <<<<<<
		}
I get a NPE on collection.getSize();

but if I code :
		if (collection != null) {
			collection.getSize();
		}

		// Delete existing values
		if (parentNode.hasProperty(jcrName)) {
			parentNode.setProperty(jcrName, (Value[]) null);
		}
everything runs fine?!
