Error using Shift TAB

When using jshell and typing pd.fill( If I press shift TAB I'm getting this error.

Unexpected character after Shift-Tab. Use "i" for auto-import or "v" for variable creation. For more information see:
/help shortcuts

I cant get the other public void for fill to appear. Anyone else having this problem?

I too am having this issue. I googled the error and this page, funny enough, is the first result. I'll come back and edit/add if I find any more information.

EDIT: So I didn't find anything online, but I realized in the next part of the video, I just hit tab instead, and it's showing the full menu, even though I only hit tab when I put in

jshell> pd.fill(                                                                                                                                                                        
void PezDispenser.fill()                                                                                                                                                                
void PezDispenser.fill(int pezAmount)         

And I'm only hitting Tab, not shift-tab. I can't explain why, but I imagine when using jshell in a non-browser environment perhaps it still needs the difference between tab and shift-tab.

Seems to work when you hold down TAB

Just hit tab twice. The first time shows the methods collapsed together. The second time will show you the signatures (including return values, name, and parameters). A third time will show documentation, if it is set up!

It's working with single TAB. jshell is really great feature in J9.

Same here

I was also having this error. Try pressing TAB only once.
