* Minimum JPype version 1.5 (due to need of improved threading behaviour since 1.4. Nominally could have been 1.4 constraint) * When starting the JVM on a non-main thread, ensure to attach the thread as daemon, as per https://github.com/jpype-project/jpype/issues/1169. * If groupId is not specified, we raise on the client side (it was already the case that we raised on the server side)
