Answer 1

Eventually with the help of Anish worked out it was a problem with missing policy files, and was only a problem with the bundle built with AppBunder.

The jdk code really seemed to expect a conf folder in the JRE, there was one in the OpenJDk but not once once was bundled into my app with AppBundler. So I downloaded the latest AppBundler src code and rebuilt it, rebuilt my appbundle and it was fixed, the conf folder was now included and application runs without error.

Answer 2

I have tested the code on Spring Tools Suite 4, AdoptedOpenJDK Java 11.0.6, macOS catalina 10.15.4 and Maven 3.8.1

I took a part of code which was causing problem.

Example.java :

package com.example;

import java.security.KeyManagementException;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

import javax.net.ssl.SSLContext;

import org.apache.http.ssl.TrustStrategy;

class NaiveTrustStrategy implements TrustStrategy {

    public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
        return true;
    }

}

public class Example {

    public static void main(String... args) throws KeyManagementException, NoSuchAlgorithmException, KeyStoreException {
        SSLContext sslcontext = org.apache.http.ssl.SSLContexts.custom().loadTrustMaterial(new NaiveTrustStrategy())
                .build();
        System.out.println("Loaded");
    }

}

Note : I took javax.net.ssl.SSLContext.

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

The output (for Testing): No error

I have looked at this link : https://github.com/TheInfiniteKind/appbundler/

Please change the JDK/JRE to point to 11.

If problem still exists, then download the latest appbundler and try to run again.

From Oracle Documentation (https://www.oracle.com/java/technologies/javase-jce-all-downloads.html) :

Current versions of the JDK do not require these policy files.

JDK 9 and later ship with, and use by default, the unlimited policy files.

The unlimited policy files are required by JDK 8, 7 and 6 only.

You can download these policy files from the documentation link above.

I think the policy files can be missing or some other issue. Please verify.
