Versions are:
Jenkins ver. 1.466.1
Perforce Plugin: 1.3.17

The perforce plug-in is currently throwing exceptions for any changelists which have jobs attached but do not have any "closed or fixed" status associated.

I checked the code and seems like there is one more case to be checked (<-- below):

// Line looks like:
// EXT-84 on 2007/09/25 by mwille closed
// or
// EXT-84 on 2007/09/25 closed
// or
// EXT-84 on 2007/09/25
// or
// EXT-84 on 2007/09/25 by mwille <-- The new case

Adding details.hasMoreTokens() at line 136 may fix it - I have not checked it of course.

Exception thrown by the plugin is:

===== begin =====
