       * java/lang/System.java (properties): Make package private.
       * java/lang/Throwable.java (StaticData.nl): Initialize through
       directly accessing System.properties.getProperty().

       * java/lang/Throwable.java (nl): Remove static field.
       (StaticData): New private static inner class.
       (stackTraceStringBuffer): Use StaticData.nl.
