Build Identifier: 20110916-0149

I'm using awesome (https://awesome.naquadah.org/) as window manager, when i start eclipse and don't give focus to it, eclipse uses 100% and start up is not finished. As soon as i switch to the eclipse tag (even it is for only 1 second), eclipse shows the editor window etc. and everything works normal from now on.

eclipse is automatically starting on another workspace/tag with my config.
workaround is to give focus to eclipse once.

Reproducible: Always

Steps to Reproduce:
1. use tiling windowmanager
2. start eclipse (on other workspace/tag)
3. dp not give focus to eclipse

Not sure where to start with this. Moving to SWT to see if they have had any experience with "awesome".

See  http://wiki.eclipse.org/index.php/How_to_report_a_deadlock for steps on how to find out what Eclipse is doing.

There have been several variations of this bug from this time period. I cannot reproduce the issue, and the latest SWT hang we had was a webkit1 problem. Closing this ticket, please re-open if it if you experience the bug on GTK3.22 with 4.8.

GTK3.22/4.8 M7/Fedora 28.
