This test failed today of the above test while running on java11, which may be relevant:

Fix is ready but the test fails for different reason NPE after this fix. The next part is dependent on the JDK bug fix https://bugs.java.com/bugdatabase/view_bug.do?bug_id=8206355. I think this will get fixed in next JDK 11 ea build (build 11-ea+22). Latest build does not have this fix so need to wait.

The SmokeTestMonitoringWithSecurityIT#testHTTPExporterWithSSL() test looks also to be failing because of the jdk11 bug:

I've muted RestClientBuilderIntegTests.testBuilderUsesDefaultSSLContext() (only when running with jdk11) and SmokeTestMonitoringWithSecurityIT#testHTTPExporterWithSSL() on master: ae5c70e
and 6.x: e7602c6
