Always use geotoolkit specified classloader when using javax.imageio.spi.ServiceRegistry
----------------------------------------------------------------------------------------

                 Key: GEOTK-18
                 URL: http://jira.geotoolkit.org/browse/GEOTK-18
             Project: Geotoolkit
          Issue Type: Improvement
         Environment: OSGi
            Reporter: Aleksander
            Assignee: Martin Desruisseaux


I am using geotoolkit inside OSGi runtime. Problem is that several classes call

javax.imageio.spi.ServiceRegistry.lookupProviders(Class) 

which then calls sun.misc.Service.providers(Class). This one uses system classloader, which can't see geotoolkit classes (since they're encapsulated within OSGi bundle classloader). Calling providers(Class, Classloader) with classloader which loads geotoolkit class itself would work.

Since org.geotoolkit.factory.FactoryRegistry already uses explicit classloaders, I would propose that all classes use this mechanism. In particular, I've found following classes which need to change their usage:

org.geotools.filter.expression.PropertyAccessors
org.geotoolkit.filter.accessor.Accessors
org.geotoolkit.filter.function.Functions
