The whole thing is caused by Maven dependencies which pull in
com.fasterxml.woodstox:woodstox-core. The WstxInputFactory has a
@ServiceProvider(XMLInputFactory.class)
annotation, where ServiceProvider is
org.ehcache.spi.service.ServiceProvider. I didn't manage to trace the
key code section, but I do find that the
javax.xml.stream.FactoryFinder then ends up finding WstxInputFactory
as registered service provider. As WstxInputFactory is not on the
common classpath (it's in WEB-INF/lib), I assume it's the webapp
classloader which is used. Below is the stacktrace where
EncodingDetector clinit happens (I defined a
ch.want.funnel.FunnelApp$DelegatingXMLInputFactory to get
stacktraces):
Currently I'm setting
System.setProperty("javax.xml.stream.XMLInputFactory",
"com.sun.xml.internal.stream.XMLInputFactoryImpl");
to get a XMLInputFactory implementation which is on the common
loader's classpath, so the webapp can be undeployed cleanly.
So this works, right?
What if you create an empty jaxp.properties file and make it available
to the common ClassLoader (e.g. in lib/empty-jaxp.jar:/jaxp.properties)
-- does that prevent the problem?
I'm wondering if Tomcat should simply ship with an empty jaxp.properties
file to prevent this kind of thing from happening by default. If someone
wants to bundle an XMLInputFactory into Tomcat's lib/ directory and use
that, they could remove this file.
BTW that's an impressive stack trace. ;)

The EncodingDetector class, if not yet loaded, will be loaded in the
common classloader, then continue by loading the XMLInputFactory using
the webapp context, and might end up with a XMLInputFactory
implementation from a webapp-provided JAR. If that happens, the webapp
can't undeploy. (In my case, woodstox WstxInputFactory registers
itself as ServiceProvider for XMLInputFactory)
For completeness: javax.xml.stream.FactoryFinder.findServiceProvider()
is called without classloader (cl = null), and has
if (cl == null) {
//the current thread's context class loader
serviceLoader = ServiceLoader.load(type);
} else {
serviceLoader = ServiceLoader.load(type, cl);
}
I can't find anything online about memory leaks from webapp-provided
XMLInputFactory implementations, but this must be fairly common. Is my
understanding correct, or have I mis-configured something? (I'm mainly
wondering whether any XMLInputFactory-implementing JARs belong in
tomcat/lib, but again I'm not finding anything online confirming that)
Tomcat 10.1.19
JVM 17.0.10+7-Ubuntu-120.04.1
Ubuntu 20.04.6 LTS
I'm not sure how many web applications ship with an XMLInputSource, but
they definitely do exist. I'm fairly sure most applications won't set a
system property or ship with a stax.properties/jaxp.properties file to
override the default implementation, but of course if it's possible,
someone will eventually do it.
I'm curious: in your example, how are you declaring your implementation
class, and which implementation are you using?
Are you able to log in EncodingDetector.<clinit> what the value of the
thread's context classloader is? I would expect that it's using the
common classloader, as you say, and that the implementation class would
also be loaded using that same classloader.
