Configuration date_string_format of SQLite in HikariCP

We are migrating C3P0 to HikarCP \o/, everything is going fine except the configuration of a property that we want to override which is date_string_format.

Here is a bit of our old C3P0 configuration:

<bean id="defaultDataSource" destroy-method="close" class="com.mchange.v2.c3p0.ComboPooledDataSource">
      <property name="driverClass" value="org.sqlite.SQLiteDataSource" />
      ...
      <property name="properties">
         <map value-type="java.lang.String" key-type="java.lang.String">
            <entry key="date_string_format" value="${datasource.date_string_format:''}" />
         </map>
      </property>
   </bean>

And a bit of our HikariCP configuration:

<bean id="merlinDataSourceConfig" class="com.zaxxer.hikari.HikariConfig">
      <property name="dataSourceClassName" value="org.sqlite.SQLiteDataSource" />
      ...
      <property name="registerMbeans" value="true"/>
      <property name="dataSourceProperties">
         <props>
            <prop key="date_string_format">${datasource.date_string_format:''}</prop>
         </props>
      </property>
   </bean>

We got this error:

Method not found: setDate_string_format
    java.beans.PropertyDescriptor.<init>(Unknown Source)

Any idea of how to fix this issue?

Thanks
