The actual result:
As the instruction,at step 6:run jre1.8.111_b14/bin/javaws jnlp_URL, and the application could not be launched on command line, there's no response after accepting the security dialog.
By the way,there's no thus issue for test jre9

But if we cleared all the deployment cache(/root/.java/deployment/*) after running the step5, and open the JCP from JRE8, then run the command: jre1.8.111_b14/bin/javaws jnlp_URL, the application could be launched fine.
