Ah, I see this in Loader:
{code:java}
static {
final SecurityManager sm = System.getSecurityManager();
if (sm != null) {
sm.checkPermission(new RuntimePermission("getStackTrace"));
sm.checkPermission(new ReflectPermission("suppressAccessChecks"));
}
}
{code}
and I bet that {{checkPermission}} throws a {{SecurityException}} and we do not
see it.
I'm not sure why these perms are checked and not saved.
Just for grins, you could remove the static block and see what happens.
