Looks good; ship it.

To me this fix raises more questions:

1. Are there other places where we generate ACC_SYNTHETIC that should also get @Hidden annotations?

2. Should the JVM be filtering stack frames for ACC_SYNTHETIC (or ACC_BRIDGE or ACC_MANDATED) calls?  (By default?  Or perhaps as a new option?)

3. When will we have a reasonable stack walking mechanism where we can program such policies in JDK library code, instead of hacking the JVM?
