Correct. hibernate-infinispan can use Java 8. As Sanne says, Infinispan itself requires Java 8 so limiting hibernate-infinispan to > 8 really makes no sense, On Tue, Mar 1, 2016 at 3:03 PM Sanne Grinovero <sanne(a)hibernate.org&gt; wrote:

Btw., when does ORM plan to drop pre-8 support altogether? 6.0? Radim On 03/01/2016 10:18 PM, Steve Ebersole wrote: -- Radim Vansa <rvansa(a)redhat.com&gt; JBoss Performance Team

Hi Vlad, thanks for bringing that up: I mean to start a thread here among the lines of my answers on twitter. The problem I see in our little survey is that in the way it was phrased it's not providing useful data for the purpose of understanding what we should be supporting in the next version of Hibernate libraries: to ask what JVM version people are using today doesn't mean they'd upgrade Hibernate to the latest right away. The reason is that I suspect people will be more comfortable to upgrade the JVM version than they are comfortable with upgrading their stack of frameworks and libraries; so when we get to know that 37% of people (assuming the survey's sample is good enough) what I read in that is that those 37% of people will not be migrating to Hibernate 5.0 either.. they are probably all using some 4.x version or maybe even some 3.x version. Why? Because until Java 9 all versions have been extremely conservative on backwards compatibility; it's very unusual to not be able to upgrade to a newer JVM (excluding Java9 here as it actually does remove some methods for the first time in history). Frameworks however have always been more aggressive in the deprecation & removal, or simply cross-library compatibilities are often a pain, so I'm pretty sure that people will be more comfortable in upgrading JVM than their libraries: when someone doesn't even touch their JVM that's usually because changing *anything* will require extensive and complex testing, maybe break some certification, etc.. so upgrading Hibernate is even less so interesting. No wonder people want us to backport patches for so long! So we should try to understand what kind of users are going to use Hibernate 6: my bet is that it's either new projects, or teams who are comfortable enough to upgrade to the latest in early months. More will use Hibernate 6 in the following years, but at that point JDK8 adoption will be even wider for sure.. if not obsolete. Either way, do we expect these to run on a pre-8 Java? I suspect a very small minority as I can only think of some very limited reasons to do that: - you need some other dependency which doesn't even work on Java8 (very unlikely? And you're not trying to get rid of it?) - your company has some weird policies (to force an older, unsupported JDK? And yet they'd allow your team to use the bleeding edge yet Hibernate?) - they are stuck using some exotic framework -> which likely means they can't upgrade Hibernate either but will need waiting for the framework maintainer to do so. So, yes I agree Hibernate ORM should probably require Java8: we get to simplify a bit of our build and embrace some new APIs. If we suspect it's premature, we might want to collect some more data but the survey should be different.. however since I'm arguing that this one was heavily biased favouring the pre-8 results and still it shows a majority of people on 8.. maybe that's good enough to show that we should!
