Description mienamoo 2011-09-15 20:09:59 UTC 
NetBeans dev build 201109090600
JDK 7 build 147

Steps to reproduce:

1. Create a NetBeans platform module with a TopComponent (Window) and open the TopComponent.
2. Open the Tasks window.
3. Set the filter to "Default filter".
4. Click the "Show tasks for all opened projects" button if not yet in that mode.
5. Set the filter to "Show all".
6. Click the "Show tasks for currently edited file only" button.

A java.lang.NullPointerException occurs at org.netbeans.modules.java.editor.whitelist.WhiteListTaskProvider$4.run(WhiteListTaskProvider.java:321).

Another way to produce the behaviour is to first click "Show tasks for currently edited file only" and then changing the filter to "Show all" (i.e. swap steps 5 and 6 above).

I can confirm that this issue is fixed in build 201109141017. So indeed, the fix for bug #201924 has fixed this way of recreating the NullPointerException too. :)
