Method o.n.m.csl.api.UIUtils.open() calls NbDocument.openDocument() in EDT.
Maybe it's not necessary, according to javadoc in NbDocument.

Reassigning. Please evaluate, thank you.

Note: I've used exception report 674276, 685074 seems unrelated.

It would be easy if it was not in the API and did not return success status. Because of the definition, it needs to block until the document opens.

I recommend to deprecate the method, and define a method that returns Future<Document> that can be waited on, if needed.

Disk operations are slow on your computer, probably many processes working with disk.

java.io.FileInputStream.open[native]()	99.679985	3,459 ms (99.7%)	3,459 ms
