Java error when trying to join hub

[Mark Matthews]

Hi

I am trying to get a nose to join a hub and getting the following error:

[root@ie-slm-srv02 selenium]# java -jar selenium-server-standalone-3.0.0-beta3.jar -role node  -hub http://00.00.00.00:5872/grid/register

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/openqa/grid/selenium/GridLauncherV3 : Unsupported major.minor version 52.0

        at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:482)

The hub is running Windows 2012 with "Java 8 Update 101".

I have one node with Windows 2012 and "Java 8 Update 101" installed on it, and i has connected to the hub fine.

I am now trying to connect a CentOS 7 node to the hub. And keep getting the above error??

If I check the java version on the CentOS server I get the following:

[root@ie-slm-srv02 selenium]# java -version

java version "1.7.0_111"

OpenJDK Runtime Environment (rhel-2.6.7.2.el7_2-x86_64 u111-b01)

OpenJDK 64-Bit Server VM (build 24.111-b01, mixed mode)

What could be causing this error, and how can it be resolved?

Cheers

Mark

Mark,

Selenium 3 requires JDK 1.8

Please upgrade your JDK version and then try again.

Thanks & Regards
