VS code unable to create new cell while using iJAVA that is build on jshell?

Question

I am just a beginner :)
Can any one help me out??

When I click the plus sign to create a new cell in a workbook I get an error. The new cell isn't created and I see this error message in a larger than usual font.

The error message survives a restart of the kernel.

The error is gone after I restart VSCode.

The error is also gone after I save / close the file and re-open it.

code

System.out.print("hello jshell");

and then i hit alt + enter

output

hello jshell

I've added the java to Jupyter Kernel and with many tests conducted, it's an issue in VS Code:

There're many similar issues posted in GitHub and now, this function is solved in VS Code Insiders but still not in VS Code:

You can install VS Code Insider, but it may not that stable, after all it's the beta-version of VS Code. In another way, you can turn to JupyterLab, try it in browser or install it.
