IntelliJ IDEA 2018.2 EAP (Community Edition)
Build #IC-182.3458.5, built on June 26, 2018

This exception is strange. It says that NPE happened at second line of the:
public void selectionChanged(@NotNull FileEditorManagerEvent event) {
debug("selection changed " + event.toString());
The only possible NPE I can see here is event, but it can't be null. What is your plugin version? Wasn't it your custom build or smth?
The plugin version is 182.2757.2, so if I am looking right, the NPE is from:
if (_currentEditor != newEditor) _currentEditor.getCaretModel().removeCaretListener(this);
And I reproduced it:
- start IDE with 0 opened files
- open a file
-> NPE - _currentEditor is probably null
Oh crap, indeed, wrong branch :)
