build failure with Java 6.0
---------------------------

                 Key: WBRI-36
                 URL: https://jira.jboss.org/jira/browse/WBRI-36
             Project: Web Beans RI
          Issue Type: Bug
         Environment: SUN Java SE 1.6.0_06
            Reporter: Kent Tong


It fails to build with Java 6.0:

/home/kent/webbeans/webbeans-ri/src/main/java/org/jboss/webbeans/model/SimpleComponentModel.java:[60,65] incompatible types
found   : java.lang.reflect.Constructor<?>
required: java.lang.reflect.Constructor<T>

/home/kent/webbeans/webbeans-ri/src/main/java/org/jboss/webbeans/util/Reflections.java:[90,61] incompatible types
found   : java.lang.reflect.Constructor<?>
required: java.lang.reflect.Constructor<T>

/home/kent/webbeans/webbeans-ri/src/main/java/org/jboss/webbeans/util/Reflections.java:[103,61] incompatible types
found   : java.lang.reflect.Constructor<?>
required: java.lang.reflect.Constructor<T>

/home/kent/webbeans/webbeans-ri/src/main/java/org/jboss/webbeans/util/Reflections.java:[122,61] incompatible types
found   : java.lang.reflect.Constructor<?>
required: java.lang.reflect.Constructor<T>

This is because the return type of Class<T>.getConstructors() has changed. In Java 5 it returned Constructor[] but in 
Java 6 it returns Constructor<T>[].

Suggest an explicit typecast like:

	for (Constructor<T> constructor : (Constructor<T>[])clazz.getConstructors()) {
		...
	}
