JCE cannot authenticate the provider BC

  Hi,

I have downloaded the bouncycastle provider (bcprov-jdk15on-162.jar<https://www.bouncycastle.org/download/bcprov-jdk15on-162.jar>) latest builds from maven, bouncycastle website and added them to classpath and on execution I get the following stack trace. Can someone please help in resolving this. In earlier versions, we never faced any authentication issues.
