If -J is useful we arguably ought to support it in CNI wrappers.
This could be done by adding a command line option to gcj which is
passed down to jvgenmain and from there to the startup sequence.

File a PR if you think this is worthwhile... I'm not so sure myself. I think I use GCJ_PROPERTIES in those rare instances where I want this.

We could also, in this case, make a CNI toolwrapper.cc which invokes the runtime using JvCreateJavaVM().

I think its pretty questionable whether we want to add a gcj option, though. I don't think that hard-coding VM arguments into native binaries is something we would want to encourage.
