             Summary: setProperty fails silently on null maps
                 Key: BEANUTILS-519
                 URL: https://issues.apache.org/jira/browse/BEANUTILS-519
             Project: Commons BeanUtils
          Issue Type: Bug
          Components: Bean / Property Utils
    Affects Versions: 1.9.3
            Reporter: Emmanuel Bourg


Adding an element to a null map with BeanUtils.setProperty() neither result in 
an automatically instantiated Map containing the specified element, nor to a 
NullPointerException. The method simply fails and returns silently. If the map 
isn't created on the fly an exception should be thrown at least.

Here is a test case illustrating the issue:

{code}
public class BeanUtilsTest extends TestCase {
    
    private static class Bean {
        public Map<String, String> elements;
    }
    
    public void testSetPropertyWithNullMap() throws Exception {
        Bean b = new Bean();
        assertNull(b.elements);
        
        BeanUtils.setProperty(b, "elements(FOO)", "BAR");

        assertNotNull("Map is still null after calling 
BeanUtils.setProperty()", b.elements);
        assertTrue("Element not found", b.elements.containsKey("FOO"));
    }
}
{code}
