I upgraded to 3.0.2.RELEASE from 3.0.1.RELEASE and suddenly my test which was passing is suddenly failing. Here is the test:
Code:

public class SpELUtilsTest  {


	@Test
	public void testGetValue(){

		Map props1= new HashMap<String,String>();
		props1.put("key1", "value1");
		props1.put("key2", "value2");
		props1.put("key3", "value3");

		
		Object bean = new TestBean("name1",new TestBean("name2",null,"Description 2",15,props1),"description 1", 6,props1);

		ExpressionParser parser = new SpelExpressionParser();
		Expression exp = parser.parseExpression("testBean.properties['key2']");
		String key= (String)exp.getValue(bean);
		
		}
	
	public static class TestBean
	{
		private String name;
		private TestBean testBean;
		private String description;
		private Integer priority;
		private Map properties;

		
		public TestBean() {
			super();
		}
				
		public TestBean(String name, TestBean testBean, String description,Integer priority,Map props) {
			super();
			this.name = name;
			this.testBean = testBean;
			this.description = description;
			this.priority=priority;
			this.properties=props;
		}

		public String getName() {
			return name;
		}
		public void setName(String name) {
			this.name = name;
		}
		public TestBean getTestBean() {
			return testBean;
		}
		public void setTestBean(TestBean testBean) {
			this.testBean = testBean;
		}
		public String getDescription() {
			return description;
		}
		public void setDescription(String description) {
			this.description = description;
		}
		

		public Integer getPriority() {
			return priority;
		}

		public void setPriority(Integer priority) {
			this.priority = priority;
		}

		public Map getProperties() {
			return properties;
		}

		public void setProperties(Map properties) {
			this.properties = properties;
		}
		
		
		
	}

}

I am getting an ArrayOutOfBoundsException on the getValue() method.

Here is the stacktrace:
