h2. context
 * Editing Java code
 * Wanted to find all usages of a method

h2. expected / desirable
 * Select method name
 * Press *ALT / F7* 
 * See Usages pop-up
 * Press *OK*
 * Review list of uses found.
 * There is ONE as identified using {{grep}}
 * I expect Navigation and Refactoring tools to work on ALL files and 
Open/Active buffers.
 * Netbeans 8 does not force me to save or save and reopen files to rename a 
method, or find all usages, etc.

h2. actual
 * Pressing *ALT / F7* resulted in the following error:

{panel:title=ALT / F7 error}
!image-2018-04-19-12-58-53-652.png!
{panel}
 * The method immediately above this line and the method below are both private
 * I can press *ALT / F7* for those methods, no problem.
 * In addition navigation isn't working e.g. *CTRL / Left-Mouse-Click* - Jump 
to source code fails.
 * But only for that One method.

_Furthermore_ ...
 * These operations started / resumed working on the {{isNullSelectedNote()}} 
method after *Save-*ing the file.
 * In a great many cases now Navigation and Refactoring operations have Failed.
 * And later worked / Resumed working later
 * There is NO CONSISTENT pattern - However most of the time saving the file or 
All Files eventually the task seems to work (_again_)
 * On the other hand, sometimes navigation, refactoring operations work fine 
without forcing me to save a file. 
 * It is unpredictable - That can be worse than broken  sometimes!
 * 

h2. Impact
 * Had to go to a command line and run grep
 * That is not helpful for a Public method used across many projects

h2. supporting information
 * messages.log
 * screenshot
