Jenkins / Bug JENKINS-35184
Failed to load jenkins.util.SystemProperties on slaves due to ServletContext
Issue Type: Bug Bug
Assignee: Oleg Nenashev
Components: core
Created: 2016/May/27 1:46 PM
Environment: jenkins-2.6+
Priority: Critical Critical
Reporter: Oleg Nenashev

Credits to Vladimir Konnov for discovering it. Impact is unclear.

RingBufferLogHandler is beig used on the slaves side (LOG_HOLDER). SlaveInitializer writes to logs and invokes logic leading to SystemProperties usage. ServletContext class cannot be serialized at that point.

Cause:

private static final int DEFAULT_RING_BUFFER_SIZE = SystemProperties.getInteger(RingBufferLogHandler.class.getName() + ".defaultSize", Integer.valueOf(256)).intValue();

Log:

Re: Failed to load jenkins.util.SystemProperties on slaves due to ServletContext

I was able to reproduce it only by manually blacklisting the javax.servlet.ServletContextListener class in remoting.
Otherwise the gets successfully serialized to slaves in my case

ServletContextListener is available starting from javax.servlet-api-2.3 only. My guess would be that there is a conflicting library on slave, which has another version of the lib

Re: Failed to load jenkins.util.SystemProperties on slaves due to ServletContext

The impact of this bug is that Jenkins 2.x doesn't work with the JClouds plugin, which provisions slaves on CloudStack.
This is blocking our upgrade to Jenkins 2.x.

CC Andrew Bayer. Likely the plugin does not shade this API... Or not.
Maybe we need a fix in the core in order to make the implementation more robust

So I'm seeing this in mvn hpi:run but not in running the jenkins war.

doing dependency:tree on the plugin shows this:

[INFO] +- javax.servlet:javax.servlet-api:jar:3.1.0:test
[INFO] +- javax.servlet:servlet-api:jar:2.4:provided

So it looks like both are being included

I'm hitting this issue too while developing on docker-slaves plugin (only with mvn hpi:run). magnayn I also have both dependencies but javax.servlet:servlet-api:jar:2.4 is provided so it's not used in the running process. I checked the open files descriptor and it's not open.

Log:
JENKINS-35184 Servlet API dependent bits in a inner-class (#2551)

This is in order to avoid loading ServletContextListener class
from slaves classloader.

  • JENKINS-35184 Don't use SystemProperties while initializing remote agents

This rolls back the previous commit and introduces a new way to construct
RingBufferLogHandler which avoids relying on SystemProperties to get the
default size.

Adding `OnMaster` annotation does not prevent the class from being
loaded on remote agent but it gives a hint that this class should not
be used on a remote agent.

In the previous code cleaning existing log handlers, SLAVE_LOG_HANDLER
is always null, as static fields are scoped by classloader.

Re: Failed to load jenkins.util.SystemProperties on slaves due to ServletContext

We have the same failure but on our master (so not on a slave). We did an update to 2.19.2 but that didn't help. The problem hits us daily on different buildjobs without a clear pattern. A Jenkins restart helps.

I'm not sure if this actually is an issue on its own, but given we have nearly the same stacktrace I guess it is related to this.

Yes, it is related. It seems that a plugin is trying to use SystemProperties from a slave. Unfortunately, the stacktrace doesn't contain enough information to pinpoint which plugin causes this.

To get you some context, the fix which went to 2.19.2 changes the way the slave initializer get the ringBufferSize property in order to not use SystemProperties from a slave, because it's not legal (which is why the patched also added OnMaster marker to SystemProperties class)

Thanks for the info. We also suspected a plugin but are a bit lost figuring out which one causes this. Is there a log where this might be found?

Not that I know of. To find which plugin it is, you will need to find the class which triggers the load on the slave. Turning classloading logs on a slave might help or remoting layer logs.

This is the remoting channel Jenkins uses to attach to a Maven Project build.

Don't use the Maven project type. It's evil.
