should ignore last comma in annotation array

FULL PRODUCT VERSION :
java version "1.5.0_05"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_05-b05)
Java HotSpot(TM) Client VM (build 1.5.0_05-b05, mixed mode, sharing)

A DESCRIPTION OF THE PROBLEM :
According to the JLS3 (see
http://java.sun.com/docs/books/jls/third_edition/html/interfaces.html#9.7).

    NormalAnnotation:
        @ TypeName ( ElementValuePairsopt )

    ElementValuePairs:
        ElementValuePair
        ElementValuePairs , ElementValuePair

    ElementValuePair:
        Identifier = ElementValue

    ElementValue:
        ConditionalExpression
        Annotation
        ElementValueArrayInitializer

    ElementValueArrayInitializer:
        { ElementValuesopt ,opt }

    ElementValues:
        ElementValue
        ElementValues , ElementValue

So a ElementValueArrayInitializer can have an optional comma before the closing
brace. If present, it is simply ignored.

javac does not allow a comma after the last entry.

STEPS TO REPRODUCE :
Just try and compile the sample test case below (taken from annotations sample from java.sun.com)

---------- BEGIN SOURCE ----------
// Test.java
public class Test {
@RequestForEnhancement(
     id = 23,
synopsis = "Sample Synopsis",
            engineer = "Test",
            date = "9/1/2007",
)
public static void main(String[] args) {
}
}

/**
 * Describes the Request-For-Enhancement(RFE) that led
 * to the presence of the annotated API element.
 */
public @interface RequestForEnhancement {
    int id();
    String synopsis();
    String engineer() default "[unassigned]";
    String date() default "[unimplemented]";
}


---------- END SOURCE ----------
