I am getting a invalid parameter error on a Http Post request from a java client

Question

I am making HTTP Post requests from a pojo java application on the IBM I-series server.

    HttpResponse response = httpclient.execute(httppost);

I am getting this error back after about 3 seconds.

java.net.SocketException: A system call received a parameter that is not 
valid. (Read failed)

I have made sure we are using TLS 1.2 and java version is 1.8

Client side - code snippets -

CloseableHttpClient httpclient = 

HttpClientBuilder.create().setDefaultRequestConfig(config).build();
HttpPost httppost = new HttpPost("https://lb1.cardknox.com/gateway");

SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
sslContext.init(null, null, null);
SSLContext.setDefault(sslContext);

HttpResponse response = httpclient.execute(httppost); 

Note: It works fine when I use it from my eclipse workbench - I only have the issue when I run this on the IBM server.

IBM Websphere server use IBM JRE not Oracle JRE. Here is the quote.

The IBM implementation of SSLContext.getInstance("TLS") is different from the Oracle implementation.

Find below the link for this.

https://www.ibm.com/support/knowledgecenter/en/SSYKE2_8.0.0/com.ibm.java.security.component.80.doc/security-component/jsse2Docs/sslcontext.html .

Also look into the following quotes

If you set the system property com.ibm.jsse2.overrideDefaultTLS=true and you enable either SP800-131a strict compliance (com.ibm.jsse2.sp800-131) or Suite B (com.ibm.jsse2.suiteB) system properties, only the TLS V1.2 protocol is enabled.

from the below link. https://www.ibm.com/support/knowledgecenter/en/SSYKE2_8.0.0/com.ibm.java.security.component.80.doc/security-component/jsse2Docs/matchsslcontext_tls.html
