To Reproduce Steps to reproduce the behavior:

1. Create a simple spring boot application
2. Instantiate a simple annotation based client
3. Add spring-boot-starter-data-jpa

Environment (please complete the following information):

• HAPI FHIR 6.0.2 (and at least also 5.7.0)
• Spring Boot 2.7.0
• Spring Data JPA 2.7.0

Spring boot config

	@Bean
	public BasicAuthInterceptor basicAuthInterceptor() {
		return new BasicAuthInterceptor(username, password);
	}

	@Bean
	public FhirContext fhirContextDSTU3() {
		FhirContext context = FhirContext.forDstu3();
		context.getRestfulClientFactory().setConnectTimeout(20 * 1000);
		context.getRestfulClientFactory().setSocketTimeout(20 * 1000);
		return context;
	}

	@Bean
	public FhirRepository fhirRepository() {
		FhirRepository repo = fhirContextDSTU3().newRestfulClient(FhirRepository.class, serverBase);
		repo.registerInterceptor(basicAuthInterceptor());
		repo.setEncoding(EncodingEnum.JSON);
		repo.setPrettyPrint(true);
		return repo;
