The error message was swallowed...
Took me a while to fix 😅 . Can you spot the error ?
@nKiaru Not sure entirely what's going on here, but maybe close() should be super.close()?
@peterdrake you got it! It's a Java lambda Consumer, and I forgot the reference to the argument...
`opener -> opener.close()`
...creating a silent stack overflow.
BTW does anybody know how to share/format code snippets with mastodon ?
@nKiaru You do have to select "markdown" using one of the buttons under the area where you compose the toot (on the web interface).
@undefined @nKiaru qoto, at least, supports markdown, so in theory you can use `single backticks around inline code` and triple backticks for block code:
```
def f(x):
return x + 1
```
(Hmm, it seem to have lost the indentation.)
