Write access for 'others' on devices - is it normal?

Question

Hi.
After a
find /* -follow -perm -o+w
i found a lot of writable files for 'others' including a lot of devices like /devices/pseudo/arp@0:arp and so on. Is it normal?
'others' have also access to the files:
/etc/fddi.cfg # i does not have any fddi-devices
/var/mail # i always thougt that 'mail' is setgid for group 'mail' to access this directory writable
/var/preserve
/var/spool/pkg
/var/spool/uucp
ps: my os is solaris 8 7/01 x86.

I performed a similar test. The resulting files were
public class test
public static void main(String arg[])
    new test2().foo();
}and
public class test2
    private void foo()
        System.out.println("foo()");
}I got as follows:
zpalmer@nestor:~$ java test
Exception in thread "main" java.lang.IllegalAccessError: tried to access method test2.foo()V from class test
        at test.main(test.java:5)This was on Debian GNU/Linux Etch with a stock 2.6.18 AMD64 kernel and Java 1.6.0_06. Anyone else care to try their system?
