The issue of being unable to use copy and paste occurs in version 1.30.0. about vscode-java

Same here, switching to 1.29.0 works.

I can't reproduce the issue.
@mainmethod0126 @hiagorios Could you attach the Java Language Server's workspace logs ?

I'm able to reproduce this as well with VS Code 1.81.1 . The Paste API (still experimental) was updated in 1.88.0 and it broke being able to use < 1.29.0 of our extension with VS Code >= 1.88.0. We fixed it in 1.30.0 but didn't make it backwards compatible. I did confirm regular copy/paste would work as usual (without the auto-import/auto-escape behaviour).

Definitely a bug though.

Update(s):

Temporary workaround if you wish to be on 1.81.1 (1.82.0 or newer don't seem to have this specific problem) :

"[java]": {
        "editor.pasteAs.enabled": false
}

The behaviour is not the same on all version. Using the 1.30.0 extension on different VS Code versions with editor.pasteAs.enabled enabled :

1.88.0 : smart paste works
1.87.2 : no smart paste, but regular paste still works
... (all versions in between exhibit same behaviour, regular paste still works)
1.82.0 : no smart paste, but regular paste still works
1.81.1: no smart paste, no regular paste
