ArrayIndexOutOfBoundsException Loading File in Crucible Review with No Fisheye Data

When a user views a file in a Crucible review based on Fisheye data that's invalid, they're presented with an ArrayIndexOutOfBoundsException. This only happens if the underlying Fisheye data is invalid, for example if the file exceeds the 5 MB limit (FE-902).

Steps to reproduce:

1. Have Fisheye index a file that is too large (over 5MB), producing the following warning:

02:47:24 WARN  - [SubversionTest] Not indexing contents of HEAD of testing/test-bigger.xml because its size (13M) is too large (limit is 5M)

2. Create a Crucible review based on the file above, and start the review.
3. Click on the file in the Crucible review, it will show "Loading diff..." for a short time and then will eventually present the ArrayIndexOutOfBoundsException.

Ideally, the user should be presented with a message saying that the Fisheye data couldn't be loaded because of the file size limit. Attached is the full stack trace and a screen cap of the error.
