Answer by Nubian for Resolving javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed Error?

I have this problem too.

I tried almost everything by adding the SSL cert to .keystore, but, it was not working with Java1_6_x.For me it helped if we start using newer version of Java, Java1_8_x as JVM.
