Description

context

• Editing Java code
• Wanted to find all usages of a method

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.

actual

• Pressing ALT / F7 resulted in the following error:

ALT / F7 error

• 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!

Impact

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