[Hibernate] Delete bug (and fix)

[Andrea A. <aa...@li...>]

I've found a bug that causes a NPE in the Session.delete(String query)=20
implementation: if you pass a query that return no objects you end up
with an NPE. The incriminated code follows:

SessionImpl.java (line 1178)

public int delete(String query, Object[] values, Type[] types) throws=20
HibernateException, SQLException {

		if ( log.isTraceEnabled() ) {
			log.trace( "delete: " + query );
			if (values.length!=3D0)  log.trace( "parameters: " +=20
StringHelper.toString(values) );
		}

		List list =3D find(query, values, types);
		int size =3D list.size();
		for ( int i=3D0; i<size; i++ ) delete( list.get(i) );
		return size;
	}

The list.size() call fails if list is null... should look like:

	if(list !=3D null)  {
		int size =3D list.size();
		for ( int i=3D0; i<size; i++ ) delete( list.get(i) );
			return size;
	} else {
		return 0;
	}

Bye
