Eric had been requesting the JDK6 support on Twitter (https://twitter.com/esammer/status/516681461219737600). In response, SAMZA-455 was opened but not much lobbying was done there.
@Eric, is it still the case that you feel JDK6 is a hard requirement? You made a strong case in the JIRA. I note that Hadoop is currently going JDK7 in 2.7. Would it work for Samza 0.8 to be the last to provide JDK6 support? It's likely that Samza 0.9 won't be out for at least a few months, and Eric had proposed a strawman approach of continuing JDK6 support for six months (back in early November). So, it's likely that 0.9 would reasonably closely meet that timeframe and could be the first JDK7-only release... -jakob On Tue, Dec 9, 2014 at 8:39 AM, Chris Riccomini <[email protected]> wrote: > Hey all, > > We've reached a bit of an impasse between upgrading to Scala 2.11: > > https://issues.apache.org/jira/browse/SAMZA-469 > > And deprecating JDK 6: > > https://issues.apache.org/jira/browse/SAMZA-455 > > It looks as though Scalatra 2.3, which is required for Scala 2.11 support, > was built using JDK 7.
