constant NullPointerExceptions

[zazzerino]

When running cursive, I get constant messages at the bottom of the screen reporting a NullPointerException. (A new one pops up every minute or so.) As far as I can tell, it seems to work fine other than this. Here's the stack trace:

[Josh-Tilles]

I've noticed this happening too, but it seems to only occur in certain projects. I'll subscribe to this issue in case @cursive-ide wants to work out what the problematic project configuration is.

[yatesco]

I see this too - I assumed my code was just too bad :-).

[DirkArnoldt]

I have this issue, too. It occurs when I open a specific source file. Other source files work well.
The source file in question has the following namespace declaration

(ns foo.bar
  (:require foo.core)
  (:import (foo.core SomeProtocol)))

and defines a record that implements the imported protocol SomeProtocol.

[cursive-ghost]

This is fixed in the latest EAP as #1560.
