Joe, I don't have any experience in chromebook. Android is not
exact linux, the line in jeload.c
n=readlink("/proc/self/exe",arg2,sizeof(arg2));
for detecting the current path of jconsole does not work under
android because there is no such file. shared objects are usually
installed under a system folder. The files in your strace are
actually symlink to libj.so inside the system folder.
Your suggestion of using -lib parameter seems feasible. I will
take a look. You run the x86 jconsole. Is your chromebook
running a 32-bit OS?
