We are developing an RCP Application based on NB7.4 a colleague of mine got the following exception:

I'm sorry, I cannot reproduce this bug. Can you please attach IDE Log, or a test case that produces output that causes this problem?
Thank you.

Comment 2 scanti 2014-06-10 21:16:30 UTC

Sorry It happened to a colleague of mine once and we cannot reproduce it either.
We are running an NetBeans based RCP, we use the Output TopComponent to show the output of a running executable

http://hg.netbeans.org/core-main/rev/287b010a9d97

It seems that the output was truncated while the document was being updated, right after the number of lines was retrieved, but before the start of the last line was read (so the values were inconsistent).

Thank you for reporting.
