Description
The LineBodyHandlerTest.java creates and discards many clients (64).
The test has been observed failing intermittently on some systems (Windows 10) while trying to open the client's selector, apparently due to some connection limit (see below).

It seems that using a single client reduces the occurrences in which the test fails.

Fix request [17u] I backport this for parity with 17.0.7-oracle. No risk, only a test change. Clean backport. Test passes. SAP nightly testing passed.
