[JIRA] (JENKINS-51327) Random java.lang.NumberFormatException

Random java.lang.NumberFormatException

Issue Type:	Bug
Assignee:	Unassigned
Components:	core
Created:	2018-05-15 10:24
Environment:	Debian 9.4 Jenkins ver. 2.107.2 SSL Gateway + Apache HTTP Proxy
Priority:	Minor
Reporter:	Erwan MATHIEU

Hi,

I'm accessing my remote Jenkins server, with HTTPS stream passing through an SSL Gateway, then the Apache server redirecting calls to the Jenkins server.

I works well, but I regularly have the following error, when accessing any page :

java.lang.NumberFormatException: 2a01:e35:8a4a:8c0:30a6:4764:692b:f7da at org.eclipse.jetty.util.StringUtil.toInt(StringUtil.java:724) at org.eclipse.jetty.util.HostPort.<init>(HostPort.java:66) at org.eclipse.jetty.http.HostPortHttpField.<init>(HostPortHttpField.java:44) Caused: org.eclipse.jetty.http.BadMessageException: 400: Bad HostPort at org.eclipse.jetty.http.HostPortHttpField.<init>(HostPortHttpField.java:48) at org.eclipse.jetty.http.HostPortHttpField.<init>(HostPortHttpField.java:35) at org.eclipse.jetty.server.ForwardedRequestCustomizer$RFC7239.parsedParam(ForwardedRequestCustomizer.java:485) at org.eclipse.jetty.http.QuotedCSV.addValue(QuotedCSV.java:135) at org.eclipse.jetty.server.ForwardedRequestCustomizer.customize(ForwardedRequestCustomizer.java:348) at org.eclipse.jetty.server.HttpChannel.handle(HttpChannel.java:310) at org.eclipse.jetty.server.HttpConnection.onFillable(HttpConnection.java:251) at org.eclipse.jetty.io.AbstractConnection$ReadCallback.succeeded(AbstractConnection.java:279) at org.eclipse.jetty.io.FillInterest.fillable(FillInterest.java:110) at org.eclipse.jetty.io.ChannelEndPoint$2.run(ChannelEndPoint.java:124) at winstone.BoundedExecutorService$1.run(BoundedExecutorService.java:77) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748)

I have to reload the page a few times, and it eventually works, but this is very annoying as it occurs quite often.

I can give you the public URL of the server in private message if required, so that you can reproduce the error with some (bad) luck. I have reproduced it with many different users.

Thanks for your support

TBH I am not sure what our IPv6 situation is overall. Might be interesting to go with IPv4 in some of the involved components and see whether that resolves the problem.

CC Olivier Lamy. I am not sure what is IPv6 situation in Jetty, it does not look like an issue in the Jenkins codebase

So the version with the fix is available in 2.117 (https://jenkins.io/changelog/#v2.117), and it will be available in the next LTS release (2.121.1) baring major issues there.

Daniel Beck Olivier Lamy I propose to add it to the weekly changelog and mention is a whatever "IPv6 support in Jetty". Maybe useful for LTS changelog as well

Took almost through the entire LTS line to get noticed, so doesn't seem to be that big of a deal.

Ok thanks, I will test version 2.117 ASAP and tell you if that fixes the issue.

something to verify as well but there might be some bad RFC7239 header as well...

I installed version 2.122 this morning, no error so far. I'll let you know in a few days.

Unfortunately, error is still present with version 2.122. Can you tell me how to disable IPv6 ? I will try to do some tests to see where it comes from.
