Hi all,
I'm a little bit late, but I just have seen:
(1) some indentations in the patch are broken
<sigh> I missed a couple of indent-2 that should be indent-4.
And something went awry with indentation in ensureProtectedAccess.
Unfortunately the webrev didn't show this and it isn't code that was
functionally modified (I had a tab-to-space conversion issue, which is
how this got touched at all).
(2) following code snipped is repeated many times:
4 times.
+ ClassLoader cl = tclass.getClassLoader();
+ ClassLoader ccl = caller.getClassLoader();
+ if ((ccl != null) && (ccl != cl) &&
+ ((cl == null) || !isAncestor(cl, ccl))) {
+ sun.reflect.misc.ReflectUtil.checkPackageAccess(tclass);
+ }
Wouldn't it be better, to move it in a method, maybe in
sun.reflect.misc.ReflectUtil ?
It didn't seem quite worth the effort of factoring out.
The isAncestor method is also repeated but again was not considered a
worthwhile factorization.
Now that I'm writing that I'm having my doubts, but at the time it was
expedient. Looking forward this code will likely have to change again to
suit a modular world.
