[IPT] IPT bug -> MySQL

[Tim Robertson [GBIF]]

Thanks Gabe,

Can you send some sample data that shows the issue please?  If you want to send me it privately that is also fine and I will use it only for this test and then delete it.

This looks somewhat suspicious from the logs:

java.sql.SQLException: Value '0000-00-00 00:00:00' can not be represented as java.sql.Timestamp
	at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1078)

I now suspect null handling issues (e.g. null dates are not handled) if all the content is sound.

Cheers,
Tim
