Error with new CloverETL 2.0 release

Hi !

I've a problem with the new release of CloverETL 2.0. I created a custom plugin with a custom component wich looks like DATA_INTERSECTION component as it is written in the documentation.

I don't understand the error message because I put in the "require" node of my plugin.xml as you can see below :

<plugin
id="com.infodb.component"
version="1.0.0"
provider-name="INFODB">

<runtime>
<library path="infodb.component.jar"/>
</runtime>

<requires engine-version="1.9.0">
<import plugin-id="org.jetel.connection"/>
<import plugin-id="org.jetel.lookup"/>
</requires>

<extension point-id="component">
<parameter id="className" value="com.infodb.component.BufferCompare"/>
<parameter id="type" value="BUFFER_COMPARE"/>
</extension>
</plugin>

When I execute a graph it writes :
