NOTE: the libc.so and libdl.so are not part of the standard JRE; 
they are from the regular Linux distribution.

Here's what versions the Linux libraries are derived from: 
lrwxrwxrwx   1 root     root           13 Mar 22  1998 /lib/libc.so.6 -> libc-2.0.7.so
lrwxrwxrwx   1 root     root           14 Mar 22  1998 /lib/libdl.so.2 -> libdl-2.0.7.so
