I didn't really want to create a bug since it's not really an issue with the application per say.

We are running a very old version of Jenkins (and I know we need to update it). The version is 1.547. We use a URL to run commands. It's running on a Windows 2008 R2 Enterprise server with 64bit environment

Over the weekend, an update to Java was applied and we are getting the following error now.
The services are all running fine and we have restarted them as well.

Until we update Jenkins, I was thinking that we could just uninstall the new version of Java and put the old version of Java back but I don't know what it is. Can someone advise?

Thanks.
