Error on j9.6 start

[Patrick Trabocchi]

Hi all, i'm moving first steps in J and when i try to start the jconsole i get an error about an invalid argument for libj.so

I'm using Fedora 43

Any help is appreciated

I think this had been fixed in j9.7 beta.

As Bill said j9.7 beta works in Fedora 43. But if you still want to
run 9.6, install execstack with dnf. And in the j9.6 directory run:

execstack -c bin/libj.so

Everything will work fine after it, but if you update your j install
you might need to run that command again.
