Spring boot enable Https : SSL Keystore Error - spring

Question

I am trying to enable https in my spring boot application but getting 'Keystore was tampered with, or password was incorrect' error. Following are the below configuration i have in my application properties file.
server.port=8083
server.ssl.enabled=true
server.ssl.key-store-type=JKS
server.ssl.key-store=C:\\Users\\abc.jks
server.ssl.key-store-password=C:\\Users\\password.txt
However when i am using TomcatServletWebServerFactory to redirect http to https with the below configuration in application properties it works fine without any issue. application starts on http 8081 and https 8083 ports.
server.port=8083
http.server.port= 8081
server.ssl.enabled=true
server.ssl.key-store-type=JKS
server.ssl.key-store=C:\\Users\\abc.jks
server.ssl.key-store-password=C:\\Users\\password.txt
I am not able to find root cause and resolve the issue. Please help me to find out what i am doing wrong.
