Description

When the ICU library is used for date formatting in format-date() (etc), there is a multithreading bug that may cause the wrong month-name or day-name to be output.

(Specifically, instances of the ICUNumberer class are reused and shared across threads, but the class has an instance-level field "cal" which is mutable.)

The observed effect is that XSLT3 test validation-0202 produces incorrect output in about 1 in 30 runs.
