Hi there, I try to start Fuseki with the following instructions
FusekiServer server = FusekiServer.create()
.port(3030)
.add("/ds", dataset)
.build();
System.out.println("Fuseki is starting on port: " +
server.getHttpPort());
server.start();
The server starts on port 3030 but hangs on. The dataset is fine, and the port
is available. The debug logs include
11:44:11.343 [main] DEBUG org.eclipse.jetty.server.AbstractConnector - Could
not configure SO_REUSEPORT to false on

Any suggestions what might be wrong? The help will be greatly appreciated.
Thank you so much!
