The three tests:

test/jdk/java/net/httpclient/ManyRequests.java
test/jdk/java/net/httpclient/ManyRequests2.java
test/jdk/java/net/httpclient/ManyRequestsLegacy.java


have been observed failing intermittently with ConnectException on windows 10 \
machines in our CI. These tests open 20 concurrent requests each, and the suspicion \
is that when these tests run concurrently on the same machine they may cross some OS \
throttling threshold that causes the connection to be rejected.

The tests had a built-in mechanism to throttle the number of requests running \
concurrently, but it was not used. The fix is to enable this mechanism on windows, \
limiting the concurrency to 10 requests, if the first run of the test fails with a \
ConnectException. 

With this in place I am no longer observing any failure (was 1 to  3 failures for \
every 50 runs before)
