The failure would be because libec_java_load.so in turn requires
system libraries that are not found:

% ldd /usr/local/eclipse/release/lib/i386_linux/libec_java_load.so
         libc.so.6 => /lib/libc.so.6 (0x4000c000)
         /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

These are the 32bit libraries, and you don't seem to have them
in your LD_LIBRARY_PATH. Most Linux distributions should come with
both 64 and 32 bit libraries, so you may just have to adjust your
LD_LIBRARY_PATH setting.
