--- Comment #20 from Sopot Cela <scela(a)redhat.com> ---
(In reply to Daine Wright from comment #19)
I am experiencing this bug.
I cannot drag editor tabs to reorder them or rearrange the editor panes.
Fedora 22
Eclipse Mars.1 (4.5.1)
I can provide any other info that will be helpful.
Here is the error message from the Error Log immediately after the drag and
drop fails:

From the stack trace it looks like it's happening when you drop it
as the NPE
is in the drop code of the agent. Are you using upstream eclipse
(downloaded
from
eclipse.org) ?
