How to create keystore and truststore to test SSL connection with Red Hat AMQ 6.3 ?

Issue

• I have created the truststore for client and server side keystore as the documentation but receiving certificate_unknown error in logs while testing with SSL client.

keytool -genkey -alias broker -keyalg RSA -keystore broker.ks -keysize 1024 -validity 3650 -keypass password -storepass password -dname "CN=some.host.local, OU=JBOSS-AMQ, OU=TEST, OU=TEST"

keytool -export -alias broker -keystore broker.ks -file broker_cert

keytool -import -alias broker -keystore client.ts -file broker_cert

• And in the activemq.xml

 <sslContext>
            <sslContext
                keyStore="${karaf.base}/etc/.certificates/broker.ks"
                keyStorePassword="password"
                />
        </sslContext>

        <transportConnectors>           
           <transportConnector name="nio+ssl" uri="nio+ssl://0.0.0.0:61617?transport.enabledProtocols=TLSv1,TLSv1.1,TLSv1.2&amp;maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600&amp;wireFormat.maxInactivityDuration=5000&amp;keepAlive=true"/>
</transportConnectors>

• In the amq.log
