             Summary: [TESTING][JCR MOCK] MockProperty getType generates 
java.lang.ArrayIndexOutOfBoundsException when the underlying array value is 
empty
                 Key: SLING-5257
                 URL: https://issues.apache.org/jira/browse/SLING-5257
             Project: Sling
          Issue Type: Bug
          Components: Testing
    Affects Versions: Testing JCR Mock 1.1.10
            Reporter: Guillaume Douillet


Hello,

According to JCR 2.0 API, {{javax.jcr.Property.getValues()}} should throw 
{{ValueFormatException}} when the underlying property is single-valued :
{code}
 /**
     * Returns an array of all the values of this property. Used to access
     * multi-value properties. The array returned is a copy of the stored
     * values, so changes to it are not reflected in internal storage.
     *
     * @return a <code>Value</code> array.
     * @throws ValueFormatException if the property is single-valued.
     * @throws RepositoryException  if another error occurs.
     */
    public Value[] getValues() throws ValueFormatException, RepositoryException;
{code}

However, {{org.apache.sling.testing.mock.jcr.MockProperty}} implements a 
different behavior. {{ValueFormatException}} is not thrown but an array 
containing a single value is returned instead.

Here a small test case exhibiting this behavior (to put in 
{{org.apache.sling.testing.mock.jcr.MockPropertyTest}}) :
{code}
    @Test(expected=ValueFormatException.class)
    public void testSingleValueAsValueArray() throws RepositoryException {
        this.node1.setProperty("prop1", 
this.session.getValueFactory().createValue("value1"));
        Property prop1 = this.node1.getProperty("prop1");
        assertFalse(prop1.isMultiple());
        assertEquals("value1", prop1.getValues()[0].getString());
    }
{code}
