FYI javax.security.auth is in the base/compact1 module.

Hi Vinnie
I don't feel comfortable to use an interface from the
javax.security.auth package which was designed around JAAS. I am also
not sure if it will be included in the core module in jdk9.
Also, the test seems quite unnecessary. You can add one on real classes
after you update the key impl classes.
Thanks

Implementers of JCE security providers can override the default method
implementations in the Destroyable interface to allow applications to
take advantage of this new facility. We intend to update our key
implementation classes soon.
How does this change interact with the existing approaches? Some
crypto-related classes use a finalize() method to trigger overwriting
the key material.
I'm a bit worried that this old approach extends the life time of the
key material considerably (because it has to be kept around until
finalizers run). Keeping a reference to a key object just to be able
to overwrite it could have the same effect.

Hello Florian,
Depending on a finalizer is a little unpredictable so this new
approach is preferred.
I don't think it will have any detrimental impact on existing
approaches. Implementers can always
choose to destroy key material in advance of any call to its destroy()
method.
