Here's the full stack trace and some context from the logs

I don't see this in every server. I'm specifically seeing it in a Docker image for a client app I'm working on. The error seems to be coming from deep within the PDF service startup, and doesn't appear to affect the rest of the server operation.

Once CF is up, I can load that class just fine and the JVM reports that the class comes from the following jar.

/usr/local/lib/serverHome/WEB-INF/cfusion/lib/activation-1.1.1.jar

Here's how to see what JAR a class came from in case anyone is curious how I got that

writeDump( createObject( 'java', 'javax.activation.DataSource' ).getClass().getProtectionDomain().getCodeSource().getLocation().toURI().getSchemeSpecificPart() )

@priyank_adobe I can put a ticket in the bug tracker for this if you'd like, but I wasn't sure if it was related to my local setup or if there were any troubleshooting steps the engineers may want me to take which would be easier to do over Slack than in the tracker UI.

I assume it's sort of classloading issue

but without knowing how and when CF loads

activation-1.1.1.jar

, it's hard to say
