Generic signature parser fails to parse return type of
the method 'getAnnotation ' from
the class 'java.lang.reflect.AccessibleObject'.

To reproduce, run the following simple script:
-----------------------------------------------------------
#!/bin/sh
set -x

JH=/home/isl/space/Refs/jdks/jdk1.5.0-b33/solaris-sparc

cat > Test.java << EOF
import java.lang.reflect.*;
public class Test {
    public static void main (String[] args) throws Throwable {
        Class c = Class.forName("java.lang.reflect.AccessibleObject");
        Method[] ms = c.getDeclaredMethods();
        for (int i = 0; i < ms.length; i++) {
            System.out.println("method " + ms[i].getName());
            ms[i].getGenericReturnType();
        }
    }
}
EOF

$JH/bin/javac -source 1.5 -target 1.5 Test.java

This bug is reproduced on b33.

This bug cases failure of jck SignatureTest.
