If a lowercased JIRA issue key is mentioned in the commit message, when you hover it on the Activity Stream it'll show an 'Issue not found' error in the popup.

I have a JIRA issue TEST-1, and I committed the changeset with this message: test-1, fixed it

When I hover this issue key in the FishEye activity stream after the incremental indexing process runs:

• This is thrown in the logs:

  2012-02-22 16:34:59,380 WARN  [btpool0-21 ] fisheye.app com.cenqua.fisheye.logging.Logs-logWarningWithDetailToDebug - Error retrieving issue 'test-1' from JIRA server at http://localhost:8080/browse/test-1: com.atlassian.crucible.spi.services.NotPermittedException: com.atlassian.jira.rpc.exception.RemotePermissionException: This issue does not exist or you don't have permission to view it. (enable debug logging for more details)
  

• The popup displayed shows 'Issue not found'.

This error is not reproducible when I hover another commit message where the same JIRA issue key is uppercased.
