> <Export-Package>
> org.apache.mina.core.polling;version=${project.version};-noimport:=true,
> </Export-Package>
> {code}
> Therefore: org.apache.mina.core.polling.AbstractPollingIoProcessor is exported, but this class has a private internal class AbstractPollingIoProcessor.Processor that should be exported as well. But It's kind of contraction to export a private class, so the osgi classpath mechanism fails with IllegalState.
> One way to approach this problem is changing the pom.xml so:
> {code}
> ...
> <Private-Package>
> org.apache.mina.core.polling
> </Private-Package>
> ...
> {code}
