Hi Bernd, A huge +1, I would be so happy to see JDK 1.8 used everywhere in James. It would allow us to write readable code based on streams everywhere.
For your information, some modules uses a JDK 1.8 : - backends/cassandra - mailbox/cassandra - mailbox/elasticsearch - server/data/data-cassandra - server/protocols/jmap* - mpt/impl/imap-mailbox/cassandra - mpt/impl/imap-mailbox/elasticsearch - mpt/impl/imap-mailbox/external - server/container/cassandra-guice - mpt/impl/smtp You will find in the POM of those project : - a build desactivation for JDK older than 1.8. An empty jar will be produced - all the project dependencies included for JDK >= 1.8 - disable animal sniffer for JDK >= 1.8 So lambas are never used with an other JDK than 1.8. But it means having a JDK < 1.8 you can not run ElasticSearch, Cassandra, JMAP, and Guice stuff. By the way, Linagora CI triggers two builds upon our pull requests : - One in Java 6 + Spring - One in Java 8 + Guice I would love to have some POM simplification, and build simplification here.
