Why do I get "NoSuchMethodException" & "IOException upon attempt to marshall", error?

I am seeing a very large number of the errors below in my log files. Nothing seems to be causing them in the way that none of our users are seeing any errors. What could be causing them? We are running CF 8.

FYI: They are happening many times per second.

Did the error start occuring after an upgrade ?

Maybe zipscan the constituent JARs,WARs, EARs on your system for the class 'jrunx.scheduler.SchedulerService' - and see if you have multiple copies of it. [ esp. something like a JAR 'hidden' inside a WAR or something, which could have been build with an earlier version of the class].

The Java Stack suggested that the method 'cancel()' is expected by the calling class, but that method doesn't exist - suggesting that maybe it used to on an old version.

java.lang.NoSuchMethodException: jrunx.scheduler.SchedulerService.cancel()

Turns out this was caused by J2EE session variables being enabled.
