When working with a customer logset, we found that we could not paste a portion of the logs into a comment without JIRA failing to create the comment.

I am providing a sample bit of text to reproduce this. This text has a null character in it which is the root cause of this. Depending on what text editor you open the file with, the issue may or may not reproduce. Sublime Text 2 seems to cut the copy operation off at the null character, so this does not happen. Textmate reproduces it 100% of the time.

Script console:

Uncaught SyntaxError: Unexpected token < batch.js:5
e.extend.parseJSON batch.js:5
$.ajax.error batch.js:1056
o batch.js:5
p.fireWith batch.js:5
w batch.js:7
d batch.js:7

Reproduced this in AOD and SAC
