> On Linux jsvc execve() itself.
> execve() requires an absolute path as the first argument therefore use of argv[0] only works when jsvc was invoked with a full path.
> Executing jsvc as relative path fails with "jsvc error: Cannot execute JSVC executor process".
> On Linux the full path to self is very easy to find: "/proc/self/exe"
> I'm attaching a patch fixing this problem and falling back to argv[0] in case /proc is not mounted.
