Although this Luna version of Eclipse is old, it is the only one that even attempts to launch. The OS doesn't have the required files needed by the newer versions of Eclipse.

Putty is on the Windows machine with Exceed running to connect to the Linux machine were Eclipse attemts to get launched.

It is important to note that Eclipse starts. I am even able to select my Project. The next screen attempts to launch but then Eclipse and Exceed goes away.

Here is the Java Version.

> java -version
openjdk version "1.8.0_222"

Usually the X11 failure occurs if X11 forwarding is not on, but as stated above, it does indeed launch. It is possible the X11 failure is due to Exceed going a way and a postmortem error.

That fact that Eclipse does launch and crashes afterward makes me wonder if some default setting needs to change.

Has anyone experienced this?

  • "PuTTY X11 proxy: unable to connect to forwarded X server: Network error: Connection refused" looks like the important message - the connection attempt is being rejected – greg-449 Apr 30 '20 at 06:56
  • Would that be an Eclipse setting because it works fine with other applications? – Unhandled Exception Apr 30 '20 at 12:09
