> Outdated serp version: Entites with Java 8 features not mapped
> --------------------------------------------------------------
>
> Key: TOMEE-1994
> URL: https://issues.apache.org/jira/browse/TOMEE-1994
> Project: TomEE
> Issue Type: Dependency upgrade
> Components: TomEE Core Server
> Affects Versions: 7.0.2
> Reporter: Uwe
> Assignee: Romain Manni-Bucau
> Fix For: 7.0.3
>
>
> Long story short: To fix, upgrade to newest serp-1.15.1 which supports Java
> 8; the one packaged with TomEE 7.0.2 (1.14.1) only supports Java 7.
> I run TomEE Plus 7.0.2 on Java 8.
> One of my entity classes uses Java 8 Lambdas. When I deploy the application,
> TomEE will map all entities except for the one that contains lambdas. There's
> an exception from the serp library that it can't read the class in question,
> but TomEE seems to continue anyway. At runtime, the EntityManager does not
> recognize the entity.
> Replacing serp-1.14.1.jar with serp-1.15.1.jar in ${catalina}/lib fixes the
> problem - I suggest an upgrade to the new serp version in the next TomEE
> release.
