Product Version: NetBeans IDE Dev (Build 201508100002)
Java: 1.8.0_60-ea; Java HotSpot(TM) 64-Bit Server VM 25.60-b23
Runtime: Java(TM) SE Runtime Environment 1.8.0_60-ea-b25
System: Windows 7 version 6.1 running on amd64; Cp1250; en_US (nb)
User directory: C:\Users\cendrowiczm\AppData\Roaming\NetBeans\dev
Cache directory: C:\Users\cendrowiczm\AppData\Local\NetBeans\Cache\dev

Test Case --> http://services.netbeans.org/synergy/client/app/#/case/1005/suite/1639/v/1

Please experiment with several code blocks (i.e. lines 92, 93, 96), select some code blocks and move mouse over this block in order to see the tooltip.

Actually the tooltip is displayed and contains correct value. However the NPE is being thrown (please see the IDE log for the stack trace).
