Description Dani Megert 2013-11-20 10:42:56 EST

+++ This bug was initially created as a clone of Bug #418254 +++

After updating my Kepler Eclipse 4.3.0 to Service Release 1, pressing Ctrl+E (show list of opened editor) and pressing Delete button causes this problem. It was buggy with 4.3.0 as well but the bug differed a bit. With 4.3.0, when you pressed Delete on an item of Ctrl+E list, it's name was cleared in the list, but it's place in the list kept empty and it was like the item is not deleted from the list, just its name was renamed to empty string in the list.


What steps will reproduce the problem?
1. Open as many Java editor as you can, so that small icon appears at the right side of editor tabs.
2. Press Ctrl+E
3. Press Del. on an item
