const document = this._documents.getDocumentData(resource).document;

That means we don't have the document synchronised anymore... Which means that it gets disposed while/before saving. How is that possible...

[jrieken]

Actually very easy... Large files aren't synchronised and hence save participation doesn't make sense for them... Simple steps

• open a monster file > 50MB
• make changes, save it
