Jetty fails to launch with BindException in FreeBSD

[ericdahl]

I'm having difficulty running the spring-boot demo with jetty due to BindException: Address already in use errors. Port 8080 is open when I run the command.

I receive this issue 90% of the time when running on FreeBSD 10.0-STABLE with openjdk-7.55.13_4,1. I found that when debugging the problem will sometimes cause it to not occur (race condition?). It seems to work fine when I repeat the steps on a Ubuntu VM.

I've tried using 1.0.2.RELEASE , 1.0.1.RELEASE, 1.0.0.RELEASE as well with no change.

$ sockstat -4 -p 8080 # showing nothing listening on 8080

[dsyer]

Interesting (and not a platform anyone else I know uses). Does tomcat work?

[snicoll]

What happens if you download and start jetty manually with the same environment?

[ericdahl]

@dsyer - spring-boot with tomcat works well. I've been using it for a couple weeks now

@snicoll - I haven't tried vanilla/standalone jetty. I do regularly use the maven jetty plugin and the gradle jetty plugin though.

I'm willing to dig into this more, though it might be a few days.

[dsyer]

It would also be interesting to know what happens if you set "server.port=0" (since by definition there should not be a conflict in that case). It might not be the best solution for you, but it would give us a data point.

[ericdahl]

With --server.port=0 it works, with the following noteworthy lines in the startup output showing two different ports being opened:

[ecd@qk ~/repos/misc/spring-boot/spring-boot-samples/spring-boot-sample-jetty]$ java  -jar target/*.jar --server.port=0
2014-05-28 20:03:05.925  INFO 5437 --- [           main] o.e.jetty.server.AbstractConnector       : Started SelectChannelConnector@0.0.0.0:22844

My issue seems to be related to the fact that Jetty is opening its server port twice: once then closing it and then opening once again. The Tomcat version doesn't do this.

Some initial debugging was showing that the Jetty SelectChannelConnector.close() method was being called for the first call, but when it closes its java.nio.channels.ServerSocketChannel, the port changes from being associated with a file descriptor to not, but it still is there:

[ecd@qk ~]$ sockstat -4 | grep 8080
ecd      java       5463  16 tcp4 6 *:8080                *:*
[ecd@qk ~]$ sockstat -4 | grep 8080
?        ?          ?     ?  tcp4 6 *:8080                *:*
[ecd@qk ~]$ nc -lv 8080
nc: Address already in use

It seems there may be something FreeBSD specific going on, though it seems odd to me that Jetty opens/closes/opens the same port like that. Here's a simplified test case that reproduces the issue using Jetty alone without spring and start/stop/starting the server.

Although I find the start/stop/start sequence odd, this issue I'm having is not spring-boot related and can be closed..

[dsyer]

That's useful information. I think we'll keep it open though because there might be a fix in Spring Boot (e.g. if we don't start the server twice).
