Webhooks failing to bypass proxy when receiving URL is configured as a nonProxyHost in JVM configuration

Atlassian Update – 22 March 2018 Hello everyone, Pleased to announce that fix has been committed and now awaits a release. We are planning to release 7.8.2 and 7.9.0 versions in few weeks. Fix would be available for Jira 7.6.5 too, which is current Jira Enterprise release, yet the release date is unknown as of today. Details of the fix As it was mentioned - the issue was isolated in an internal component AHTTP-36 . Upgrading the component inside the product resolves the issue. Fix has been tested Jira versions 7.6.5, 7.7.3, 7.8.2, 7.9.0.   Upgrading While it is possible to upgrade a component out of band - Atlassian recommends upgrading to nearest bugfix release to get the fix.  Out-of-band component upgrades may lead to support team reject support cases until Jira code and plugins is in original versions.  Also out-of-band deployments also may have a critical impact on instance stability and performance because of JRASERVER-64908 . In any case - I'm attaching the mentioned version of the component that contain the fix - atlassian-httpclient-plugin-1.0.1.jar, which may be upgraded if the mentioned risks are tolerable.   Configuration Please mind that there are different proxy configuration options available for http and https (http.proxyHost, https.proxyHost). All the details are available in https://confluence.atlassian.com/jirakb/how-to-configure-an-outbound-http-and-https-proxy-for-jira-applications-247857187.html   Wish you a smooth upgrades.
