Original comment by Shelley Lambert in the July 2024 General Retrospective:

x64 Windows: com/sun/net/httpserver/simpleserver/CommandLinePositiveTest.java and simpleserver/jwebserver/CommandLinePositiveTest.java are problematic for JDK22 and JDK21, address in use failures

I can't. I've posted a request in the Slack channel.

So it's intermittent. Feels like the tests are affected if ports are used by other processes. Should be excluded or not?

[steelhead31]

After some investigation, the problematic command in the test is this..

00:03:42.529  [simpleserver]:c:\jenkins\workspace\Grinder\jdkbinary\j2sdk-image\bin\jwebserver.exe -b ::0
00:03:42.529  [simpleserver] Error: server config failed: java.net.BindException: Address already in use: bind

This command tries to start a java webserver without a specified port or address, which is localhost, but with port 8000.. this port is already in use by the incredibuild web dashboard ( which is not required on test machines ). I'll investigate disabling this service on the test machines, or switching it to a different port.
