@dstepanov Hi! Look to this, pls

[altro3]

CI-CD is ok, just some problems with github action:

Does it fix something for Java as well? Maybe you can add a test for it too

Hey, opener of #10505 here. How exactly does this fix the issue? I'm a little bewildered that all it is is changing how strings are concatenated (double quote vs single quote) and using empty strings from utils. My java skills are definitely not the strongest, but here I feel there is some hidden java knowledge I am just not aware of? 😅

[dstepanov]

@hrothwell It looks like the same issue that @altro3 is fixing

[dstepanov]

Thanks @altro3!

[hrothwell]

@dstepanov yes it is the issue @altro3 is fixing, I am wondering how this fixes it. I am unsure of how just updating some string concatenation is fixing the issue.

I am asking more for my own knowledge and curiosity.

Main confusion: what is the difference in the end result of string1 + "." + string2 and string1 + '.' + string2 in java? Are these not the same?

[dstepanov]

Those are just code improvements, the main fix is return Optional.of(StringUtils.EMPTY_STRING);

[hrothwell]

So the main difference then just being a static empty string vs putting in a new "" empty string? Values are the same, so I guess the only other thing it could be is that static vs non-static?

see below

Ah wait I missed a line, sorry about that. Thanks for pointing that out @dstepanov
