Calling EJB causes error in CF Administrator

Question

Hello,
I just moved from CFMX 6.1 Enterprise to 7 Standard and now
I'm having trouble when I invoke an EJB. The EJB returns the
information successfully, but then when I try to access the CF
Administrator, the following error is shown:
Security: The requested template has been denied access to
D:\WebSites\mntwia01\CFIDE\adminapi\administrator. cfc. The
following is the internal exception message: access denied
(java.io.FilePermission
D:\WebSites\mntwia01\CFIDE\adminapi\administrator.cfc execute)
ColdFusion cannot determine the line of the template that caused
this error. This is often caused by an error in the exception
handling subsystem.
The rest of the website works fine, but I need to restart
ColdFusion in order to be ablet to access the administrator again.
The problem happens with every EJB I call, and only since the move
to CF 7.
Thank you for any suggestions,

This error seems to happen if you are debugging a function (or any subprogram with OUT parameters) and the debug call block does not assign the function's return value (and/or OUT parameters) to bind variable.
The default call block generated by SQL Developer for debugging a function ends with a statement like:
:v_Return := v_Return;
assigning the return value from the function call to a bind variable.
If you remove this bind variable entirely (say, because you used the "From File" option to load some existing script for calling the function in question), then you get the "Invalid Column Index" error. Presumably SQL Developer expects to be able to get the return value of the function out of a bind variable, so if there is nothing to bind to it gets an error.
Now, there doesn't seem to be any very good reason for this, since as far as I can tell you can't view the return value in any way after completing the debug run (and in fact, in many debug runs you may not even run the function to completion).
