iDRAC JNLPException Security Error

Question

Hello,   I am using Centos 7 and Firefox to try and launch the console of a Dell iDRAC. I am using Java version '1.8.0_131', Java(TM) SE Runtime Environment (build 1.8.0_131-b11), Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode).    When I connect to the iDRAC and click to launch the console it fails to open.  When I click launch to open the console I accept the Security Warning.  It says, Trying to launch iDRAC6 Virtual Console Client from Dell Inc. It asks, Do you want to Continue. The connection to this website is untrusted. I click 'continue'.   The box with the error stated, 'Unsigned application requesting unrestricted access to system. The following resource is signed with a weak signature algorithm MD5withRSA and is treated as unsigned: https://address/software/avctKVM.jar'.   The Exception is below: JNLPException[category: Security Error : Exception: null : LaunchDesc: https://1.1.1.1:443' spec='1.0+'>       iDRAC6 Virtual Console Client     Dell Inc.     https://1.1.1.1:443/images/logo.gif' kind='splash'/>             ip=1.1.1.1     vmprivilege=true     helpurl= https://1.1.1.1:443/help/contents.html     title=idrac-GJVDXQ1%2C+PowerEdge+R610%2C+User%3Anyiadmin     user=572660336     passwd=1159126505     kmport=5900     vport=5900     apcp=1     version=2                     https://1.1.1.1:443/software/avctKVM.jar' download='eager' main='true'/>         https://1.1.1.1:443/software/avctKVMIOWin32.jar' download='eager'/>     https://1.1.1.1:443/software/avctVMWin32.jar' download='eager'/>         https://1.1.1.1:443/software/avctKVMIOWin64.jar' download='eager'/>     https://1.1.1.1:443/software/avctVMWin64.jar' download='eager'/>         https://1.1.1.1:443/software/avctKVMIOWin64.jar' download='eager'/>     https://1.1.1.1:443/software/avctVMWin64.jar' download='eager'/>         https://1.1.1.1:443/software/avctKVMIOLinux32.jar' download='eager'/>     https://1.1.1.1:443/software/avctVMLinux32.jar' download='eager'/>         https://1.1.1.1:443/software/avctKVMIOLinux32.jar' download='eager'/>     https://1.1.1.1:443/software/avctVMLinux32.jar' download='eager'/>         https://1.1.1.1:443/software/avctKVMIOLinux32.jar' download='eager'/>     https://1.1.1.1:443/software/avctVMLinux32.jar' download='eager'/>         https://1.1.1.1:443/software/avctKVMIOLinux32.jar' download='eager'/>     https://1.1.1.1:443/software/avctVMLinux32.jar' download='eager'/>         https://1.1.1.1:443/software/avctKVMIOLinux64.jar' download='eager'/>     https://1.1.1.1:443/software/avctVMLinux64.jar' download='eager'/>         https://1.1.1.1:443/software/avctKVMIOLinux64.jar' download='eager'/>     https://1.1.1.1:443/software/avctVMLinux64.jar' download='eager'/>   ]     at com.sun.javaws.security.JNLPSignedResourcesHelper.checkSignedResourcesHelper(Unknown Source)     at com.sun.javaws.security.JNLPSignedResourcesHelper.checkSignedResources(Unknown Source)     at com.sun.javaws.Launcher.prepareResources(Unknown Source)     at com.sun.javaws.Launcher.prepareAllResources(Unknown Source)     at com.sun.javaws.Launcher.prepareToLaunch(Unknown Source)     at com.sun.javaws.Launcher.prepareToLaunch(Unknown Source)     at com.sun.javaws.Launcher.launch(Unknown Source)     at com.sun.javaws.Main.launchApp(Unknown Source)     at com.sun.javaws.Main.continueInSecureThread(Unknown Source)     at com.sun.javaws.Main.access$000(Unknown Source)     at com.sun.javaws.Main$1.run(Unknown Source)     at java.lang.Thread.run(Thread.java:748)   Is it possible to resolve?

I switched to openSUSE-Tumbleweed and it works.

HOW can that be a solution?

I needed to access DRAC on Dell C2100 server & with Windows 10 / Java 8 201 it is no longer possible.

So I had to get Win 7 in VM with Java 7 80 & that worked.

So not a solution at all, but rather a workaround!
