CDI JavaDocs link to Extension Architecture broken

It appears that the Java SE team have moved their "Extension Architecture" documentation. This invalidates the link in the CDI JavaDocs we publish as follows:
In the file:
cdi-api-1.2-sources\javax\enterprise\inject\Vetoed.java
Is a link in the meta data for JavaDoc:
<a href="http://download.java.net/jdk8/docs/technotes/guides/extensions/spec.html#sealing">
Which returns <404>, file not found.

I suspect this is now moved to:
https://docs.oracle.com/javase/8/docs/technotes/guides/extensions/spec.html

But I can't be sure because there's no Anchor titled "sealing" in that moved document.
