I had a look at some similar questions here on Meta:

 * https://meta.stackexchange.com/questions/108734/should-i-ask-a-new-question-or-edit-the-existing
 * https://meta.stackexchange.com/questions/103517/edit-code-or-post-new-question

...but they don't really fit the problem I have, which is the following:

I [asked a question on SO](https://stackoverflow.com/questions/15377243/eclipse-console-lines-missing-from-the-end), which hasn't attracted any answers yet, just some comments. [Based on a comment](https://stackoverflow.com/posts/comments/21733714?noredirect=1), the code sample I posted to replicate the problem doesn't seem to be very effective.

Now, by accident, I found another, shorter code sample which seems to be more effective to reproduce the problem and therefore I'm wondering if I should edit the existing question or start a new one with the new code sample?
