----------------------------------------
Hi Dawid, will check now.
I haven't seen any failure on Windows or Mac (unfortunately it is hard to check
as the exception is not part of mail text). The Gradle-Runer VMs are also
different, because 9.x uses Java 11.0.14 and main uses JDK 17.0.1.
What is also interesting, it is always the same file with this ICU license
header. No other file seems affected by this!
One hint I can give: The hardware is AMD Ryzen, not Intel like most other CIs
and there could indeed some different behaviour with multithreading. It also
has many CPU cores, while the Apache Jenkins server are just virtual machine,
no hardware.
