javax.net.ssl.SSLHandshakeException: PKIX path building failed

[Alekhya]

Hello, 

I have been getting javax.net.ssl.SSLHandshakeExceptions intermittently ! This used to work before ! Suddenly started experiencing these issues ! I get below issue as a warning while building apnsclient and get below issue as error at sendNotificationFuture.get() .  I retry 3times if notification fails to send. so , it sometimes work while retrying !  I could not figure out the reason for this issue ! This issue is happening for VOIP push. notifications, But APNS notifications works fine ! Need some help to resolve the issue . Thanks in Advance !
