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

The properties file I'm working with is a message bundle of a java gui application, which has a total of 7,500 lines (containing a lot of comments and blank lines and roughly 5000 properties).
Since this real file contains confidential data from a customer project, I'm attaching a dummy message bundle with 5000 properties which shows the same effect.

To reproduce:
Open the file with the JBoss Tools Properties Editor and try navigating by PgUp/Down or mouse and input stuff on several places while having the Outline view open. You will experience significant delays in the visual response to your actions up to a point where fast input from keyboard shows characters slowly one after another.
Now close (not minimize) the Outline view and the performance will increase significantly, comparable to the behaviour in the regular Properties File Editor.

My setup is eclipse Indigo 64bit SR2 on Kubuntu Linux 12.10 with according JBoss Tools version from eclipse Marketplace. But as I said before, the same behaviour shows on Windows 7 and/or another eclipse version.

> unfortunately I can't provide a recipe to reproduce the problem.
> However: It seems to happen when:
> I open 2 properties files - each about 300 lines
> I have the properties files open for some time (not using it) 
> then I add a line and save it: in this case eclipse is stuck for 1-2 seconds. 
> I only have about 300 properties in the editor.
