Re: [Wrapper-user] What is the best way to handle JRE updates on end user computers

Bundling the JRE is definitely gets my vote. If you made your application
auto-updating then that would handle the ability for your customers to
obtain timely security fixes.

Any other kind of solution is ultimately a hack with all sorts of problems
that can arise not the least of which is that customers can install a JRE
that your application may not be compatible with. We had a similar
situation where users were upgrading JREs galore (which is not always what
you want) causing all manner of problems. Bundling the JRE would have fixed
that but we ended up switching to a web based application instead. Life has
been a lot easier since.
