To fix this problem, compile your package with AUTHID CURRENT USER
directive in the Package Signature.
Basically when user B executes package of user A, for the course of
the package's run user B becomes user A and the ownership context is
that of user A's. When user B runs show_user(tablename), effectively
ORacle is trying to resolve tablename in user A's namespace....which
is doomed for failure. Worse if A, B and C both have tables with the
same name, you will be reporting incorrect results (always A's
tables).
