I figured this out, in case anyone else needs a solution in the future.
The issue was caused by the precompiled Java Service Wrapper not
supporting the specific ARM architecture on the Pi.
Here's the steps I took that rectified the issue (and other issues
along the way):
1. Install Oracle's JDK instead of openjdk/jre (you'll need the jdk
for later steps)
2. Install ant
2. Download the latest Java Service Wrapper source from
http://sourceforge.net/projects/wrapper/files/wrapper_src/
3. Set your environment's $JAVA_HOME and $ANT_HOME to the locations of
jdk and ant. If you mess those up, the wrapper compiler will tell you.
4. Compile the wrapper (run build32.sh)
5. Copy the generated wrapper executable in the bin directory to the
wrapper dir in Freenet, replacing the current wrapper-linux-armhf-32
exec in Freenet's bin
6. Copy the .so file from the lib dir into Freenet's lib as
libwrapper-linux-armhf-32.so
7. Finally, jar up the org dir in the classes dir - jar cf wrapper.jar org.
Copy the new wrapper.jar file into Freenet's dir.
I *think* you can skip the last step if you compile the same version
of the wrapper as the one used in Freenet. I think currently it's
3.5.20 while the latest wrapper is 3.5.23.
And finally, enjoy the perpetually high load on your pi while freenet
is running :).
I'm not sure how practical this is in the long run but it was fun
trying to get it to work.

Hi all,
Just wondering if anyone has ever tried running Freenet on raspberry pi.
I have the 512 MB ram model with a 700 MHz ARM processor and trying
to run it, I get Segmentation fault.
Is this simply a case of not enough resources?
Did an strace on the execution and here's what I get (if that is of
any help):
read(10, "tmem -le 1024 ] \n then \n "..., 8192) = 1616
stat64("memory.autolimit", {st_mode=S_IFREG|0644, st_size=4, ...}) = 0
write(1, "Starting Freenet 0.7...\n", 24) = 24
stat64("/media/usb/Freenet/./Freenet.pid", 0xbed07778) = -1 ENOENT
(No such file or directory)
stat64("/usr/local/sbin/nice", 0xbed07918) = -1 ENOENT (No such file
or directory)
stat64("/usr/local/bin/nice", 0xbed07918) = -1 ENOENT (No such file
or directory)
stat64("/usr/sbin/nice", 0xbed07918) = -1 ENOENT (No such file or
directory)
stat64("/usr/bin/nice", {st_mode=S_IFREG|0755, st_size=26240, ...}) = 0
clone(child_stack=0,
flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD,
child_tidptr=0xb6fd3068) = 16725
wait4(-1, [{WIFSIGNALED(s) && WTERMSIG(s) == SIGSEGV}], 0, NULL) = 16725
--- SIGCHLD (Child exited) @ 0 (0) ---
sigreturn() = ? (mask now [QUIT])
write(2, "Segmentation fault\n", 19) = 19
exit_group(0) = ?
Thanks.
