PrivilegedAction et al and JEP411

[Peter Firmstone]

Will the removal process be traceable using a bug ID or JEP, until it's 
completely removed, rather than bit rotted out over time?

After much thought and consideration our best option is to maintain our 
own build, by maintaining patches against the upstream OpenJDK build, 
this will allow us to run all existing jtreg tests, as well as implement 
new tests and prevent bit rot.

Support for SM will also be removed from jtreg, so we'll need a build of 
that too.

This should at least secure our future roadmap until an alternative exists.
