Problem

When creating a review for a file that comes from a Perforce repository Fisheye/Crucible throws a NullPointerException and the following appears in the atlassian-fisheye.log

2015-04-29 14:00:00,000 WARN  [qtp1491126818-31907 ] fisheye StreamIndexedLineReader-guardLineNumber - unknown line number 13 only know about 12 in P4:Perforce:Repo/path/to/file

javax.servlet.ServletException: java.lang.NullPointerException

Cause

This issue is usually due to mixed line endings which confuses Fisheye.

Resolution

1. Go to FishEye/Crucible Administration > Repositories and open the repository configuration.
2. At SCM Details set the option Disable Multiple Print.
3. At Maintenance, under Repository Source Index, click Start for Re-index. This will rebuild the indexes for this repository from scratch.
