Camel 3.21 & groovy scripting - Class loading errors

[Ephemeris Lappis]

Hello.

I'm migrating camel projects from old Camel 2.x to Camel 3.21.

Camel routes are deployed as OSGi blueprints to be executed in Karaf.

I have a strange exception I had not before about some Groovy classes
that are not found while the groovy scripts seem to be executed.

My bundle manifest declares a dynamic import for groovy scripting (and quartz) :

DynamicImport-Package =
        groovy.*,
        org.codehaus.groovy.*,
        org.apache.camel.pollconsumer.*

But classes in package groovy.xml are not resolved as expected.
Statements like this :

<setProperty name="myAliceXML">
<groovy>new groovy.xml.XmlParser().parse(request.getBody(File.class))</groovy>
</setProperty>

Fails with the following error :

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Script_bb14d11f44acc4f9bf59e5db81b864e4.groovy: 3: unable to resolve
class groovy.xml.XmlParser

When I check exports and imports, all seems to be ok :

admin@root()> exports | grep groovy.xml
groovy.xml
                          │ 3.0.8             │ 883 │ groovy

admin@root()> imports | grep groovy | grep 975
groovy.*
                          (0x                  │            │ 975 │
caterpillar-switch
org.codehaus.groovy.*
                          (0x                  │            │ 975 │
caterpillar-switch

What has changed in groovy scripting that could be the cause of these
errors ? It seems the script classloader doesn't include the dynamic
import.

Thanks for your help.

Regards.
