Summary 0005277: IllegalArgumentException during loadClass
Description There appears to be a race condition where 2 servlets initializing are attempting to call definePackage on the same package.

definePackage throws IllegalArgumentException if the package is already defined.

We're synchronized on the ClassEntry but not the package.

There is a check for the package in DynamicClassLoader.loadClassEntry using getPackage, but it looks like a race condition is possible.
