NoClassDefFoundError: org/bouncycastle/crypto/tls/TlsFatalAlert

In BouncyCastle 1.68 this class seems to be renamed to org.bouncycastle.tls.TlsFatalAlert

Hi. Thanks for notifying. Current release is using 1.59 and as result does not has a problem. Whenever we will work on new release we will take that into account
