From 8627cdf300d3c9643d0a88b37a81d8d02aa2dfd7 Mon Sep 17 00:00:00 2001 From: Thomas Darimont Date: Mon, 18 May 2015 17:53:26 +0200 Subject: [PATCH] DATAJPA-658 - Improve metadata detection for xml based entity mappings. We now honour purely xml based entity definitions, e.g. via rm.xml. Previously we only checked the annotations for detecting id properties.
