[jdk11u-dev] RFR: 8251361: Potential race between Logger configuration and GCs in HttpURLConWithProxy test

[Aleksey Shipilev]

This backport is simple, but it does not apply cleanly to 11u due to context conflict with "8227539: Replace wildcard address with loopback or local host in tests - part 20". It brought `throws Exception` to `main` method. I resolved that conflict by hand.

Additional testing:
 - [x] Affected test still passes
