> The {{Jcr}} class is the entry point for configuring a JCR repository using an Oak backend. However, it always use a hardcoded set of dependencies ( IndexEditorProvider, SecurityProvider, etc ) which cannot be reset, as they are defined in the constructor and the builder {{with}} methods eagerly configure the backing {{Oak}} instance with those dependencies.
> As an example
> {code:java|title=Jcr.java}
> @Nonnull
> public final Jcr with(@Nonnull SecurityProvider securityProvider) {
> oak.with(checkNotNull(securityProvider));
> this.securityProvider = securityProvider;
> return this;
> }
> {code}
> injects the security provider which in turn starts configuring the Oak repository provider
> {code:java|title=Oak.java}
> @Nonnull
> public Oak with(@Nonnull SecurityProvider securityProvider) {
> this.securityProvider = checkNotNull(securityProvider);
> if (securityProvider instanceof WhiteboardAware) {
> ((WhiteboardAware) securityProvider).setWhiteboard(whiteboard);
> }
> for (SecurityConfiguration sc : securityProvider.getConfigurations()) {
> RepositoryInitializer ri = sc.getRepositoryInitializer();
> if (ri != RepositoryInitializer.DEFAULT) {
> initializers.add(ri);
> }
> }
> return this;
> }
> {code}
> Instead, the {{Jcr}} class should store the configured dependencies and only configure the {{Oak}} instance when {{createRepository}} is invoked.
