Need help on TLS 1.2 https service call from Java 1.4 client - ssl

Question

I am facing issue while calling RestAPI call (which is running on Java 1.8 and TlS 1.2) using postmethod call from Java 1.4 client application. I have written below client code and I am end up with below issue.
I am providing the required .jks files in both trust store and keystore.
Error:
>java.security.KeyStoreException
>at com.ibm.jsse.bg.<init>(Unknown Source)
>at com.ibm.jsse.bo.a(Unknown Source)
>at com.ibm.jsse.bo.engineInit(Unknown Source)
