ClassCastException after opening a Twig template

See original GitHub issue

I’ve encountered the following error: when I open a Twig template and switch back to a PHP file within the same session, after that whenever I click in that file, I get a ClassCastException.

Q	A
PhpStorm version	10.0.2 build: PS-143.1184
JRE	1.8.0_51-b16 amd64
Plugin version	0.11.106
Project type	Symfony fullstack
PhpStorm EAP channel	no

This issue is probably related to #592

After I restart PhpStorm, the issue is gone until I open another Twig file.

Stacktrace:
