Description

During normal usage (typing Java code) NB 11.3, after trying to select a proper method overload from code completion list an error occurs. Code completion is invoked on a third-party library (Vert.x). I did not change NB after installation.

1. Selected method is not added to text/content in the editor.
2. Choosing other methods from code completion list works only for methods without arguments.
3. Restarting NB does not help.
4. Reloading the project does not help.
5. Closing the project, then restarting NB and reopening the project does not help.

What helped: deleting current line of code and using code completion on a native Java class like String (no restrictions here regarding method arguments). After that code completion started to work again on objects from third-party library.
