Autocomplete feature problem 'File Not Found' error

I have a basic java code where I am using inheritance.
It seems like extension is unable to get doc-strings and other verbose information.

As compared to the normal execution where when you hover over the object instance or class name you are given the various details of the constructor, in this case it doesn't.

Although the code works but all the autocomplete features gets disabled.

The server says File Not Found

Environment

• ElementaryOS:
• javac 1.8.0_171:
• 1.23.1:
• 0.25.0

Folder with all files to reproduce error

The log file is in the folder.
The error seems to come from Car.java file in the Demo.java file.

Descarga la carpeta de reproducción enlazada en el issue e inspecciona su registro, comenzando por la interacción entre Car.java y Demo.java. Reproduce el error File Not Found en la Java extension y luego rastrea la solicitud de autocomplete o hover que falla; se considera terminado cuando los tipos heredados proporcionan documentación e información detallada sin desactivar autocomplete.
