Description

Currently, clojure.lang.DynamicClassLoader's constructor has the
following call to super():

super(EMPTY_URLS,
      (Thread.currentThread().getContextClassLoader() == null ||
        Thread.currentThread().getContextClassLoader() == ClassLoader.getSystemClassLoader()) ?
          Compiler.class.getClassLoader() : Thread.currentThread().getContextClassLoader());

That call to ClassLoader.getSystemClassLoader() is forbidden by Google
AppEngine's security policies. That restricts you from being able to
load any resources from the classpath that haven't been AOT-compiled.
I've verified that just removing that removing the " ||
Thread.currentThread().getContextClassLoader() ==
ClassLoader.getSystemClassLoader()" does in fact result in something
that works in GAE (as far as my needs go). Unfortunately, I'm not sure
whether that breaks anything, which, presumably, it does.
