Alan, Karen,
Can you review the fix for:
6612680: Remove classloader dependency on jkernel
Webrev at:
http://cr.openjdk.java.net/~mchung/6612680/
java.lang.ClassLoader and sun.misc.Launcher have explicit dependencies
on the jkernel code. While the performance impact of this is minimal
(the calls basically amount to nops when the JRE is complete), it's
still undesirable.
To eliminate the static dependency on jkernel, this adds a boot
classloader hook interface that is invoked in the ClassLoader
findClass, getSystemResource, and other methods. The hook is null by
default. The jkernel VM will call the static
DownloadManager.setBootClassLoaderHook() method and only the jkernel
environment will have a non-null boot class loader hook. Since
jkernel is a separate build including the bundles and VM, as we
discussed, the jkernel VM is a reasonable place to inject the
DownloadManager as the boot class loader hook.
I'm hoping to make TL b74 which is code freeze by 10 pm PT Monday.
Thanks
Mandy
A small comment, it seems that DownloadManager.instance is never read.
cheers,
Rémi
