java.lang.Thread

    private char name[];

    public final void setName(String name) {
        checkAccess();
        this.name = name.toCharArray();
    }

    public final String getName() {
        return String.valueOf(name);
    }

On the surface, set/getName() are not correctly synchronized,
getName() could observe a partially filled char array
