Description Nicolas Bros CLA 2010-12-15 11:04:09 EST 
Often, when I have made many changes and I try to undo a lot of changes at once, I keep the "Ctrl+Z" keys pressed for a few seconds, which triggers a lot of modifications in a short amount of time.
After this, I often find that the contents of the editor have become corrupted, resulting in a state that was never present in the editor at any one time.

For example, sometimes some lines become truncated at the end in the editor.

configuration

This is with:
Eclipse SDK
Version: 3.7.0
Build id: I20101208-1300
JRE version : 1.6.0_22-b04

But I also noticed this problem a few times with older versions of Eclipse.

I have attached the complete configuration.

I cannot provide a simple way to reproduce, since the problem seems random, with a low frequency.

Do you need more information?

In which editor do you see this?

Anything in .log?

In the Java editor (CompilationUnitEditor).

> Anything in .log?
no, nothing related

I'm sorry but so far no luck to reproduce. Without steps or an error in the .log we can't do anything. Please reopen if you have more precise steps to reproduce.
