Clifford Dann commented on PDFBOX-4671:
---------------------------------------
Deleting the logging will not solve the complete problem, as the problem will
move onto the cache with exactly the same problem, as in that the class that
has been brought back is not meant for the Class loader that is currently
running, and so will fail in a JEE container environment, too see if the actual
problem has been solved you would have to run it on a tomcat server with more
than one war file and each war has JBIG2 included in them, the above code gets
around, this, the correct solution, would be what ever fetches the Class, gets
it from the correct place.

> JBIG2 ImageIO plugin sometimes does a NoClassDefFoundError
> I'm using TwelveMonkeys IIOProviderContextListener to fix the problem of
> ImageIO with servlets, and additionally doing a
> {{ImageIO}}.{{scanForPlugins}}(). But this keeps happening randomly. Any idea
> where could be the problem ?
> This is happening with Tomcat 7 running over Oracle Java 8 (latest version)
