Description kosmonaffft 2012-10-15 07:53:49 UTC 
This bug was originally marked as duplicate of bug 199170, that is already resolved. This bug is still valid, so this seems to be another bug, but it might be related.

Build: NetBeans IDE Dev (Build 201210140002)
VM: Java HotSpot(TM) 64-Bit Server VM, 23.3-b01, Java(TM) SE Runtime Environment, 1.7.0_07-b10
OS: Windows 8

Stacktrace: 
java.lang.NullPointerException

Comment 2 Andrew Krasny 2012-11-28 20:23:47 UTC 
Easy to reproduce in debugger.
Breakpoints:
(a) org.netbeans.modules.cnd.navigation.overrides.BaseAnnotation:214 (attach())
(b) org.netbeans.modules.editor.lib2.document.CharContent:89 (length())

Activate (a), once it is hit (just open a c++ file with annotations), activate (b). Step Out; in NB remove all the text from a file; Save it; Release debugger => NPE 

document.getEndPosition() could return null.

Proposed patch is attached.
