You don't want the -I part.

I'd try stracing gcj to find out what's going on

 $ strace -f -etrace=file gcj -c HelloWorld.java

This will tell you where gcj is looking for its jarfiles.  Look for
something like this:

...
547   execve("/home/aph/gcc/trunk/install/libexec/gcc/x86_64-unknown-linux-gnu/4.5.0/ecj1", ["/home/aph/gcc/trunk/install/libe"..., "Hello.java", "-g1", "-fbootclasspath=./:/home/aph/gcc"..., "-g1", "-fsource=1.5", "-ftarget=1.5", "-fzip-dependency", "/tmp/ccXyDB9d.zip", "-fzip-target", "/tmp/ccipPqBc.jar"], [/* 42 vars */]) = 0
...
547   stat("/home/aph/gcc/trunk/install/share/java/ecj.jar", {st_mode=S_IFREG|0644, st_size=1377431, ...}) = 0
547   open("/home/aph/gcc/trunk/install/share/java/ecj.jar", O_RDONLY) = 3
...
