             Summary: DefaultJdbcPrepareStatementStrategy Iterator fails on null valuer inserts
                 Key: CAMEL-7803
                 URL: https://issues.apache.org/jira/browse/CAMEL-7803
             Project: Camel
          Issue Type: Bug
          Components: camel-jdbc
    Affects Versions: 2.13.2
            Reporter: Nathan Wray


The iterator returned by createPopulateIterator in DefaultJdbcPrepareStatementStrategy reports "hasNext() == false" when it encounters a map value of null.  This happens when using the map header JDBC_PARAMETERS = "CamelJdbcParameters" to insert null values with a prepared statement.  The Iterator ends prematurely when it reaches a parameter name with a null value.  

For example, passing in a map where the 3rd parameter of 19 has a value of null causes the following exception to be thrown:

java.sql.SQLException: Number of parameters mismatch. Expected: 19, was:2
