Java Logger and Splunk Class HttpEventCollectorLoggingHandler not working, forwarding to HEC + Splunk

[steveIMS]

I reduced content of my documentation of problem (Code and Trace), due to request from Splunk,

I'm trying to log to the Splunk via the HEC using java.util.logging and Splunk Handler Class HttpEventCollectorLoggingHandler.

The events don't appear to be forwarded to Splunk. Also It looks to stopping in the SSL Handshake; I have a GUID specified in the properties file; the properties used for the Splunk Class are echoed out in the console log.

Logging to a different HTTP listener look to work OK; my play Java Http listener to echo sent logger data,

The Java Program Source and the Console Log, are pasted below.

Using Eclipse Java Development environment; Build Path has the following Jar Files:

• splunk-sdk-java-1.6.5.jar
• okhttp-3.12.8.jar
• okio-1.13.0.jar
• com.google.gson classes

I'm also using splunk-library-javalogging-1.8.0.zip classes, for classes not included in the splunk .jar file.

The program compiles clean.

It looks to stop in the SSL handshake after "done seeding SecureRandom"; last entry in the console log.
I'm running with these arguments passed to the program, for debugging and properties file,

-Djava.util.logging.config.file=C:\Explorer_Exports\jdklogging.properties -Xdebug -Djavax.net.debug=all

Was wondering if I'm using the proper .jar files in build path; classes from the .zip file, or my logger setup may be incorrect.

Any assistance would be appreciated. Steve.
