PCClassFileTransformer.isEnhanced() fails because PersistenceCapable package name is wrong
------------------------------------------------------------------------------------------

                 Key: OPENJPA-68
                 URL: http://issues.apache.org/jira/browse/OPENJPA-68
             Project: OpenJPA
          Issue Type: Bug
          Components: jpa
         Environment: Win32, JDK1.5, OpenJPA 0.9.0-incubating
            Reporter: Corey Klaasmeyer
            Priority: Critical


On line 201, the fully qualified interface name should be "org/openjpa/enhance/PersistenceCapable"
not "openjpa/enhance/PersistenceCapable":

    /**
     * Analyze the bytecode to see if the given class definition implements
     * {@link PersistenceCapable}.
     */
    private static boolean isEnhanced(byte[] b) {
        ConstantPoolTable table = new ConstantPoolTable(b);
        int idx = table.getEndIndex();

        idx += 6; // skip access, cls, super
        int ifaces = table.readUnsignedShort(idx);
        int clsEntry, utfEntry;
        String name;
        for (int i = 0; i < ifaces; i++) {
            idx += 2;
            clsEntry = table.readUnsignedShort(idx);
            utfEntry = table.readUnsignedShort(table.get(clsEntry));
            name = table.readString(table.get(utfEntry));
            if ("openjpa/enhance/PersistenceCapable".equals(name))
                return true;
        }
        return false;
    }
