I have gone through multiple threads here on Stackoverflow and added all the required truststore, truststoretype system properties. This thread I have tried. But nothing is working. Has anyone come across this ? I am invoking it like below

TrustManagerFactory tmf = TrustManagerFactory
.getInstance(TrustManagerFactory.getDefaultAlgorithm());

KeyStore ks = KeyStore.getInstance("BCFKS");
ks.load(new FileInputStream("<jre-home>\\\\lib\\\\security\\\\cacerts"), "changeit".toCharArray());
tmf.init(ks);

// Get hold of the trust manager
X509TrustManager x509Tm = null;
for (TrustManager tm : tmf.getTrustManagers()) {
if (tm instanceof X509TrustManager) {
x509Tm = (X509TrustManager) tm;
break;
}
}

Answer

This was resolved when we moved the AWS-client initialization to a place after setting the trust store password. In my code, I was creating AWS-Client too early.
