[jdk17u-dev] RFR: 8298931: java/net/httpclient/CancelStreamedBodyTest.java fails with AssertionError due to Pending TCP connections: 1

[Goetz Lindenmaier]

I backport this for parity with 17.0.17-oracle.

Resolved Copyright in ISO test.
It's already at 2023, while this change updates it to 2022. 
So probably a review is needed.
