a bug of JDBC 10.2 with JDK 1.5

Oracle (the database software) let a bad piece of data in. Oracle says the client should type the data when binding. I agree. But I also think that the server shouldn't let non-numeric data into numeric columns, regardless. I contend that this is a bug on the server side as well as a bug on the client side. This is only one specific case of a Java program inserting bad data.

ORA-3136 WARNING: inbound connection timed out

A possible cause may be SGA latch contention 
The theory is that while the shared_pool was being re-sized in the SGA, Oracle grabbed a latch. The memory resize operation took a while and while Oracle held that latch, nobody could login.
