No more data to read from socket

This is a very low level exception, which is ORA-17410.
It may happens by several reasons:
  1. A temporary problem on networking.
  2. Wrong JDBC driver version.
  3. Some issues with special data structure (on database side).
  4. Database bug.
In my case, it was a bug we hit on the database, which needs to be patched.
