Start with test/jdk/java/net/httpclient/websocket/security/WSURLPermissionTest.java, especially testWithAllPermissions at line 379, and review the linked test output for the proxy timeout and connection refusal. Run the WSURLPermissionTest security-policy configuration on Java 11 Alpine Linux and compare the failing case with the preceding successful cases. Done means the networking test completes without the connection-refused failure.
