Probably worth mentioning that to reproduce this issue, you have to include Apache's HTTP Client ( |

With this change, the SSL certificates that are provided by the system are picked up by default when using the
RestTemplateBuilder.This aligns with the implementation of
new RestTemplate()which is already doing this, and can be considered a follow-up to a previous (partial) fix from 5 months ago relating to this issue.(For context,
RestTemplateis usingSimpleClientHttpRequestFactoryby default, which appears to be picking up the SSL certificates from the environment)In our Cloud Foundry environment, where the SSL certificates are provided by the system through a build-pack, we encountered a problem with SSL certificates. The SSL certificates from the system work fine with
new RestTemplate(), but not withnew RestTemplateBuilder.build(). This seems unintentional, especially considering a previous (partial) fix that added some functionality (throughuseSystemProperties()) but missed the SSL properties.As I am quite new to the Java & Spring Boot ecosystem I am not entirely sure how to best test this, but the issue we are facing seems to be a spring-boot issue to me, which can hopefully be fixed with my PR.
