Delay Repositories initialization in DomainClassConverter [DATACMNS-1734]

[spring-projects-issues]

Oliver Drotbohm opened DATACMNS-1734 and commented

As reported here the initialization of Repositories during a call to DomainClassConverter.setApplicationContext(…) can cause deadlocks in the context of deferred infrastructure initialization. In the example given, the initialization of the Spring Data JPA MappingContext implementation tries to access the Metamodel provided by the EntityManagerFactory, currently in creation in a separate thread.

We could delay that initialization until the first actual use of the converter to avoid this
