Fwd: error

[Eugene Sirota <zh...@gmail.com>]

Hello.

> 
> I have a storage plugin set up for Oracle RDBMS ( using jdbc driver ) and on one particular schema ( and seems only one ) if I try to run show tables, I guess NullPointerException ( as shown below ).
I tried many other schemas but only one gives this issue. I even tried remotely debugging through the code and it seems RPC get is returning a failure result but again I cannot understand why.
Any pointers would be greatly appreciated.

Thank you
