RestTemplate SocketException: Connection Reset using Java 7 but not Java 8

Question

When executing an HTTP POST using Spring RestTemplate, I get a java.net.socketException: Connection Reset

However, when I execute the identical code on Java 8 the same code works without issue. I've not found any similar issue related to this.

Can someone point me to anything I might be doing wrong? I've tried even using the command line arguments like -Dhttps.protocols=TLSv1.1,TLSv1.2

Nothing has worked so far. Any assistance would be appreciated

Here is my code:

String xmlResponse = null;
if (restTemplate == null) {
    CloseableHttpClient httpClient = 
    HttpClients.custom().setSSLHostnameVerifier(new NoopHostnameVerifier()).build();
    HttpComponentsClientHttpRequestFactory requestFactory = new 
    HttpComponentsClientHttpRequestFactory();
    requestFactory.setHttpClient(httpClient);
    restTemplate = new RestTemplate(requestFactory);
}
HttpHeaders rqHeaders = new HttpHeaders();
rqHeaders.setContentType(MediaType.TEXT_XML);
HttpEntity<String> createAppRequest = new HttpEntity<>(xmlRequest, rqHeaders);
ResponseEntity<String> responseEntity = restTemplate.exchange(datasafeURL, HttpMethod.POST, createAppRequest, String.class);

Results:

Issue was that the endpoint required TLSv1.2 and by default Java7 runs TLSv1.1

Configuring the restTemplate to use TLS1.2 solves this issue.

    if (restTemplate == null) {
        try {
            SSLContext context = SSLContext.getInstance("TLSv1.2");
            context.init(null, null, null);
            CloseableHttpClient httpClient = HttpClientBuilder
                    .create()
                    .setSSLContext(context)
                    .build();
            HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory(httpClient);
            restTemplate = new RestTemplate(factory);
        } catch (Exception e) {
            log.error("could not create SSL Context - cause::: {}", e.getMessage(), e);
            throw new CustomException(e);
        }
    }
