To work around this error, I usually re-run eclimd or, or sometimes I run headed eclipse just once and exit out of it.

And often when I try to re-run eclimd, I get the following error in an endless loop:

I'm pretty sure this issue has been fixed on the git master branch.

Hello Eric,

I can confirm that this error is appear in current release of eclim (1.7.13).

I enough often reproduce it.

My environment is:

$ uname -a
Linux desktop 2.6.32-45-generic #102-Ubuntu SMP Wed Jan 2 21:53:06 UTC 2013 i686 GNU/Linux

Ubuntu 10.04

Eclipse 3.7 from website (not from ubuntu's repository)

$ java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) Server VM (build 20.1-b02, mixed mode)

Thank you,

Alexey.

Do you have set of steps that can reliably reproduce it?

Ultimately this shouldn't be a problem any more with juno and eclim
2.x, but if I have a way to trigger this issue then I'll take a look
into trying to find a fix.

Is it eclipse 3.7 and not 3.7.1 or 3.7.2? What is the output of
:PingEclim?

I just want to make sure that if you do provide a way for me to
reproduce this, that I attempt to do so on the proper eclipse version.

I am having the same problem. I tried eclimd 2.3.4 with eclipise 4.4 and got the same problem. Did you find
workaround for this problem.

Here is top 5 frames of the stack trace.

Have you found any workaround for this problem?

Unfortunately problem still persist in juno and eclim 2.x (eclim 2.3.4)
I am using JDK 1.7.0_51

[Basant Kukreja]

I solved this issue. I think this is a problem with X display remote message. If eclimd tries to open up a warning message window, eclimd sends this error.
Note that DISPLAY variable was setup correctly and terminal was able to windows like xterm/gvim etc.

I logged into the machine using nomachine and started eclimd. Fixed the warning issue which it was complaining and then eclimd started without any issues.

After that eclimd worked in regular ssh console too.

Thanks,
Basant.

Interesting, thank you for the updated. Do you recall what the warning
message was? At one point, when updating eclim for the eclipse 4.x e4
apis, I tried to suppress all gui modals/windows, not just the root
window, but I was unable to get that working. I'll make a note to try
that again since more than one of eclim's dependencies have a knack for
throwing up dialogs (adt, scalaide, pydev) at startup.

It started working but now I rebooted the box and the problem appeared again. Now it doesn't seem to be related with X display.

----------------------------------------------

So there is something going on which I don't understand. I don't really know why it doesn't able to find the class? Is it something related to oracle jdk/open jdk on
ubuntu? Above message is with Oracle jdk.

- Basant.

[Basant Kukreja]

It started working again. But there are many caveats which I don't understand.

First of all I need to use Oracle java else it doesn't work.
Second I have to start eclipse, let it initialize, then close it. Then when I start eclimd, it works, it may be just coincidence.

I am not even confident if I stop eclimd and restarts it, it will work again. Any trick how to diagnose where the problem is?
