Hi,
still has an extended CFP till Monday, April 30.
I proposed two topics, one related to MP Metrics, so if others would like to participate, I am sure they accept multiple speakers (and judging from last year I trust each speaker gets a free pass unlike EclipseCon ;-) The keynote by Adam Bien even mentions Jakarta EE or MicroProfile, so if others have some topics to propose, give it a try. The conference is among the bigger Java events in Germany/Central Europe. And has both Oracle and Eclipse Foundation as top sponsors.
There is also a dedicated Cloud day which could be a good fit for MicroProfile topics.
Regards,
Werner
