Bug 327699

Description Michael OBrien 2010-10-13 14:34:20 EDT

>Getting the following on one machine view without any overrides of the 2.0 spec jar and 1.6 compile level in jpa.test
JPA2: SimpleSerializeFetchGroupTests find(,,Map) may report Type mismatch error on expected Employee not Object
>1 of 4
Description	Resource	Path	Location	Type
Type mismatch: cannot convert from Object to Employee	SimpleSerializeFetchGroupTests.java	/eclipselink.jpa.test/src/org/eclipse/persistence/testing/tests/jpa/fieldaccess/fetchgroups	line 884	Java Problem

>Fix is to use generics like other tests in the file

For the JPA 2.0 spec function
    public <T> T find(Class<T> entityClass, Object primaryKey, Map<String, Object> properties); 

>Compiling
        Map<String, Object> properties = new HashMap<String, Object>();
        Employee emp = em.find(Employee.class, minId, properties);

>broken
        HashMap hints = new HashMap(2);
        Employee empShared = em.find(Employee.class, id, hints);

>Trivial Fix is to specify generics in the map
        HashMap hints = new HashMap(2);
to
        HashMap<String, Object> hints = new HashMap<String, Object>(2);
or
        Map<String, Object> hints = new HashMap<String, Object>(2);
