I don't think this relates to your code as you don't have any stub indices.

[lisachenko]

@artspb but there are lines in trace from my plugin:

at com.aopphp.go.pointcut.PointcutAdvisor.getMatchedElements(PointcutAdvisor.java:95)
at com.aopphp.go.line.marker.AdvisorLineMarkerProvider.collectNavigationMarkers(AdvisorLineMarkerProvider.java:53)

So maybe there should be some synchronization between threads, etc...

[artspb]

No, not really. It seems that the stub index is corrupted for some reason. Do you have the .gitignore plugin installed BTW?

Also, you can rewrite this code using PhpIndex. It also relies on the stub index but has one huge advantage: it's backed by the cache.

No, I haven't.

This could be interesting ) But if I remember correctly, stub index was recommended for use, because it is fast, isn't it? Or PhpIndex use additional runtime caching?

[lisachenko]

Removed the "bug" label because it doesn't relate directly to the plugin and is not reproducing in new versions of PhpStorm.

Yes, PhpIndex does basically the same as you do but with additional in-memory cache which is shared between all its users.
