8266036: class file for sun.misc.Contended not found

[lahodaj]

[this is an improved version of openjdk/jdk PR:
https://github.com/openjdk/jdk/pull/4428
]

The ct.sym may contain classfiles referring to annotations that are not present in ct.sym (liek JDK's internal annotation sun.misc.Contended). If javac will try to load them (while discovering annotations for the purpose of detecting which annotation processors should be run), an error will be produced (please see the issue). The proposal is to strip annotations that are not present in ct.sym when generating ct.sym.

As noted by @jddarcy, we also need a special handling of ValueBased, which this patch should do, so it also solves https://bugs.openjdk.java.net/browse/JDK-8258421

[jddarcy]

I was wondering how better to document that the addition of new JDK-specific annotation types might require more updates to this list.

Perhaps adding notes in the existing annotation types would help, as people might cut-and-paste the old types when creating new ones. That may be more effective than adding package-level documentation on the internal packages.

@jddarcy thanks for the comment, and sorry for delays. I've updated the annotation with a note on the special annotations, as suggested. Does the text make sense? Thanks!
