I'll take a look at those changes to see if they could be ported back to the the 3.0.X stream. Rookie question, but what is the major difference between the 3.0.X stream and 3.1.X stream? Does 3.1.X require Java 8 (or higher)? 3.0.x supports Java 6+, 3.1.x - Java 7+, master (3.2.0-SNAPSHOT) - Java 8+ Cheers, Sergey Thanks, Andy On Wed, Aug 17, 2016 at 10:48 AM, Sergey Beryozkin wrote: Hi Andy Welcome, thanks for the introductions, some comments below On 17/08/16 15:56, Andy McCright wrote: Hi All, I wanted to introduce myself.
