I have added my full stacktrace here http://pasted.co/97aa6cb4, please review and let me know if you find the problem
I can provide more details if you want, can anyone help why is this happening? and how to solve this?

Answer 1

Try specifying the first argument in the JKSKeyManager's constructor which is a org.springframework.core.io.Resource, the implementation that seems to fit best with your config value is a org.springframework.core.io.ClassPathResource.
cpResource(ClassPathResource, conf.saml.keyManager.storeFile )
keyManager(JKSKeyManager,
ref('cpResource'),
conf.saml.keyManager.storePass,
conf.saml.keyManager.passwords,
conf.saml.keyManager.defaultKey)
