I have successfully upgraded to EMM 505. I am running in multi-user mode, on Windows server 2012R2 with Tomcat 7.0.55 and MYSQL backend. On the server itself I can open the Protégé repository in server mode, edit, and publish to the viewer. On my client, I can connect to the remote repository, open it, edit and save them successfully. However when I try to publish to the repository from the client, it fails with the error "Exception in thread AWT-EventQueue-0" and sun.java2d.HeadlessGraphicsEnvironment cannot be cast to sun.awt.Win32GraphicsEnvironment."
Is this because of the difference in Java versions between the client and the server? On the server I am running Java 1.7.0_67 and on my client I am running 1.8.0_51. If this is the source of my problem, should I upgrade the entire server to 1.8 or should I downgrade my client to 1.7? I am hoping that the upgrade is the correct answer, since I hope to deploy the client to other workstations where I may not be able to control the Java version.
Thank you in advance for your reply.

Hi,
Thanks for posting.
This could well be a Java version issue but I think it would be worth looking into the error message a bit more.
Could you post more details of the exception message / stack to see where this error is being thrown?
Getting the JVMs to a roughly compatible level makes a lot of sense, here. There can be some incompatibilities. Unless you have many existing users running on Java 7, it's probably worth getting the server upgraded to Java 8 in line with your workstation.
Either way, it would be great to get a detailed message from the exception to help us identify the issue.

Thank you.
Sorry, I probably should have said that the previous trace was generated on the server. On the client, I get this:

Hope that helps.
