Christopher Tubbs commented on ACCUMULO-891:
--------------------------------------------

Due to the thrift issue, I can make the list immutable, but not the actual ByteBuffers.

> Instances of {{Authorizations}} are not actually immutable, despite the API making it seem like they are. A user can make changes that will write-through to the backing data by using the ByteBuffer getter.
> This is a potential issue if a trusted application acts as a connection broker between accumulo and untrusted clients.
