Eclipse Search Results are Missing When there are Exactly 404 Matches?

Specification

• Eclipse: SpringSource Tool Suite
• Version: 2.9.1.RELEASE
• Build Id: 201203221000

What I do:

1. Search -> File
2. Containing text: "subheading"
3. File name patterns: "*, !*jquery.js, !*min.js"
4. Scope: Workspace
5. Click 'Search'

What I expect to happen:

• The Search tab will show search results for "subheading".

What happens:

• The Search tab starts to find results and puts them on the tab.
• The number of matches stops at 404 since there are exactly that many instances of "subheading" in my workspace.
• The file/directory names of each result turns blank.

My Suggestion For Duplicating:

• Make a test workspace with exactly 404 instances of a word.
• Search for it.

My Theory:

The developers of Eclipse are messing with me. I hope this isn't true, but I don't see why else it would do this. Can anyone else duplicate this and/or explain it?

Update:

After much more use of Eclipse, this same result seems to randomly occur (file/directory names turning blank). It happens consistently when there are 404 results, but it also happens randomly with other amounts.
