[jdk11u-dev] RFR: 8308336: Test java/net/HttpURLConnection/HttpURLConnectionExpectContinueTest.java failed: java.net.BindException: Address already in use

[Anton Bobrov]

This is a backport of JDK-8308336: Test java/net/HttpURLConnection/HttpURLConnectionExpectContinueTest.java failed: java.net.BindException: Address already in use

It is required to be applied on top of the backport for JDK-8054022 / https://github.com/openjdk/jdk11u-dev/pull/2523 to 11u-dev to avoid intermittent test instability issues.

The patch applies clean.

Testing: x86_64 build, affected test
