I don't see any problem with adding an option to LoaderInterceptor11 to force it to use a SimpleClassLoader (the descendent of AdaptiveClassLoader) even on a Java2 platform. There are some trade-offs, since SimpleClassLoader is really meant for Java1.1 platforms, but for a lot of people they don't look too serious.
This is a little bigger decision than I want to make on my own, so I've included the Developer List in the reply in case one of the other developers has comments/suggestions. ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Saturday, January 05, 2002 6:47 PM Subject: Possible Explanation - Re: DO NOT REPLY [Bug 5684] - WEB-INF/lib jar file loading and operations problems. > Hi Bill, > > I downloaded the 3.3 source code and did some sniffing.
