[appengine-java] Re: Load order WEB-INF/classes not always before WEB-INF/*.jar?
Hey Marc, We're not aware of this being a problem. As far as we know, we're conforming to the standard by preferring classes in WEB-INF/lib. Can you reproduce this definitively? For example, check the value of TheHtmlUnitClassThatYouAreShadowing.class.getCodeSource().getProtectionDomain().getLocation(). If you can provide a sample app that shows this behavior, that would be great.

Hi Toby, thanks for the quick answer. I'll open an issue if I'm able to make the problem reproducible. Cheers, Marc. Toby Reyelts a écrit : Hey Marc, We're not aware of this being a problem.

If you can send your app-id (privately if you want), we'll see if we can investigate some on our end.
