Hi, Thanks. It is too early as the program already final and the conference takes place in about a month, but maybe next year for those whose company or clients are happy to send them to the US more than once DevNexus ( https://devnexus.com) could be an interesting option. Reza talks about Java EE. And many Java Champions show up on the agenda. Also a few from Europe or Brazil. Whether they provide funding for independent speakers not sent by their companies I can't remember. I met somebody from the OC at the Champions BBQ before JavaOne. Explains the lineup, but it seems among the bigger community driven Java and Developer conferences in North America.
Cheers, Werner
