Hi,

I am facing a strange bug when using Oracle JDBC driver 12.1.0.2 .

From time to time, connecting the database fail with the following exception:

I googled and found a documented issue which seems to be exactly the bug I faced. Doc ID is 2394036.1 .

However, there is no access to the full information and solution about this bug.

Can anyone help?

Thanks

Thanks for your answer.

On top of the database? Isn't it an Oracle JDBC driver bug, i.e. client-side?

I don't know, this is what is said, if you want more information you have to ask Oracle itself.
