Start in CVECheckService.java at retrieveVulnerabilityData(), then trace its callers through fetchCves(), getCveUpgradeIssues(), and batchGetCVEIssues(). Reproduce the GitHub Security Advisory API failure in the reported IntelliJ, Linux, JDK, and plugin versions; done means vulnerability data retrieval no longer produces the reported SSLHandshakeException.
