It does not show different numbers for me.  One possibility could be
that your environment is different (e.g. LANG) and so different classes
are loaded (given you're not using the same terminal to run the
program).

What program is this?  You can try -XX:+PrintSystemDictionaryAtExit and
compare the output of a C1 and C2 run.
