Service Builder OSGI modules with external datasource definition doesn't work anymore with Liferay 7.1.1 GA2.

The services are connected to the internal Datasource (confirmed by creating missing tables in it).

There was no trouble with LP 7.1.0 GA1.

Not the only one with that trouble (cf https://community.liferay.com/forums/-/message_boards/message/111742415)

here is how my ext-spring is defined, following thisd guide : https://dev.liferay.com/de/develop/tutorials/-/knowledge_base/7-1/connecting-service-builder-to-external-databases

   <!-- To define an external data source, the liferayDataSource Spring bean

       and liferayTransactionManager may optionally be overridden.

   <!-- In service.xml, we associated our entity with the extDataSource. To
