Eclipse hangs directly after startup in "Credential Migration Ui Job" [message #1797966] Fri, 09 November 2018 04:50 Go to next message
Eclipse UserFriend
Today I encountered a weird problem that never happened before. I created a new workspace, and after the Eclipse main window opened I see in the lower right of the window the activity message "Credential Migration UI Job". The mouse cursor is spinning, and I only can kill Eclipse after that. Recreating the workspace didn't help. Existing workspaces are not affected by the problem.

This happens on macOS Sierra with a current Eclipse installation:

Version: 2018-09 (4.9.0)
Build id: 20180917-1800

Any idea what could cause this, and whether there's a fix or workaround?

Thanks
Stephan

Could you use `jstack` to obtain a stack trace? There are details at: https://wiki.eclipse.org/How_to_report_a_deadlock

While I was able to reproduce this problem several times last Friday, the problem is gone now. The only difference is that the machine was shut down in between.

If the error occurs again, I will get a stack trace.

Ah, the traditional CS solution fixes many problems :-)

Now it happened again. I have attached the stack trace.

So your main thread is blocked trying to update the "Launch Bar"'s status, which is trying to get a list of Docker images from a a registry.

It sounds like bug 536317. See the final comment for ways to workaround the bug and apply a patch.

Thanks for the hint. I do in fact have Docker installed and I also have CDT with the "C++ Docker Container Launch Support". But the bug report says that an update to CDT 9.5.1 should fix the problem. If I understand the "Installed Software" information correctly, I already have CDT 9.5.4 installed.

Ruhroh! Sounds like you should open a new bug! Does the workaround still work?

Right now the problem is not reproducible. I come back when it happens again.
