Java programmatically add custom trusted + default certificates using SSLContext setDefault
Using a custom truststore in java as well as the default one with SSLContext setDefault
In this video we are going to setup truststore load certificates in it programmatically and then include all the certificates from JDK default lib/security/cacerts bundle as well and then set our truststore as default via SSLContext.setDefault method.

9:36 Second test case that creates truststore programatically and then calls URL with untrusted root certificate
11:20 Third test case that calls google.com but gets PKIX exception since using custom truststore cleared the default certs
