When class is declared with type parameter

   class Test <X extends I>
   
but I is an interface (not a class) type, generic signature parser
fails to parse this type parameter.

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
public class Test<X extends I> {
    public static void main (String[] args) throws Throwable {
        Class c = new Test().getClass();
        c.getTypeParameters();
    }
}

interface I {}
EOF

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

Class.getTypeParameters() fails with stack dump
