Re: [hibernate-dev] Null-Pointer Exception with 5.2.14

Hi Petar, You can use this template: http://in.relation.to/2016/01/14/hibernate-jpa-test-case-template/ to create a test case that replicates the issue. You don't need to provide all entities, just the 4 entities that build that hierarchy you have mentioned in your email. If you can replicate it, please open a Jira issue and attach the test case so that it's easier to investigate the cause and provide a fix. Thanks, Vlad On Thu, Mar 1, 2018 at 10:41 AM, Petar Tahchiev <paranoiabla(a)gmail.com&gt; wrote: > Hi Christian, > > My model has more than 250 entities big.
