>          Issue Type: Bug
>          Components: Data Model & JPA Backend
>    Affects Versions: 5.1.1
>            Reporter: Kohei Nozaki

> In entry deletion, invocation of IndexManagerImpl#addEntryReIndexOperation() occurs and it assumes WeblogEntry.pubTime is present but it's null if it is a unpublished entry.
> I think there's no impact for regular use but it seems like not intended behavior so I think adding simple null check is reasonable.
> Step to reproduce:
> 1. Save a new entry as draft
> 2. Delete the draft
> Exception:
> ERROR 2015-02-08 09:39:10,152 WriteToIndexOperation:run - Error acquiring write lock on index
> java.lang.NullPointerException

>         at java.lang.Thread.run(Thread.java:745)
> UPDATE:
> I found an another problematic situation. following procedure brings NPE at the same point:
> 1. Publish a entry
> 2. Save same entry which is published as a draft (back to draft)
> 3. Publish the entry again
> It has possibility of making some un-indexed content so it should be fixed.
