Android Question Regex in B4A 9.30

[peacemaker]

HI, All
Before update to B4A 9.30 this sub worked OK:

Sub IfFormattedQR (text As String) As Boolean
    Dim res As Boolean = Regex.IsMatch("\d{4,}", text)
    Return res
End Sub

Strings like "TEST0000", "TEST9999"... were matched OK, as on https://regex101.com

After update to B4A v.9.30 ... it's a miracle - do not match anymore.
Always at jdk-11.0.1.
Am i ill ?

TEST0000 is not a match for \d{4,}.
0000 is a match.

You can change the pattern to \w*\d{4,} or use Regex.Matcher instead of Regex.IsMatch.

Thanks, Erel, but.... before at https://regex101.com and in code it was matched, i remember...
But "\w*\d{4,}\w*" works now, thanks.

i tried it. With the defaults it does not match.
If you change the site to use a matcher then it works.

The code from the first post will not "work" (return true from TEST0000) with any version of B4A. You can try it.
It cannot "work" because TEST0000 doesn't match the pattern.
