CI Build Environment ISO-8859-1 versus UTF-8

As stated in the referenced dev mailing post, the Jenkins CI environment uses a default charset of ISO-8859-1 on its build nodes.

However, we have one test, which uses German umlauts in a date formatter (specifially in March --> März) in openejb-cxf-rs specifically TomEEJsonbProviderTest
