Paul Grey commented on NIFI-9826:
---------------------------------
The Github CI for the project runs regular builds (with unit tests) using
multiple locales. This is currently implemented by specifying system
properties for the locale in the CI Maven command line, and configuring the
root POM to propagate the locale settings to surefire.
It may be possible to specify the CI locale via an environment variable (such
as `LC_ALL`). If Maven and Surefire can accept specification of an alternate
locale in this way, the `pom.xml` settings could be reverted.
