I was wrong in my assumptions. It's possible to export classes having inner
class.
For example I tested in simple bundle activator:
{code}
SimpleBufferAllocator simple = new SimpleBufferAllocator()
simple.wrap(ByteBuffer.allocate(1))
{code}
and it's work out of the box.

The key is to instruct maven-bundle-plugin to export all packages hierarchy.
For example this could be more generic solution for mina-core/pom.xml:
{code}
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<inherited>true</inherited>
<extensions>true</extensions>
<configuration>
<manifestLocation>META-INF</manifestLocation>
<instructions>
<Bundle-SymbolicName>${project.groupId}.core</Bundle-SymbolicName>
<Export-Package>
org.apache.mina.core*;version=${project.version};-noimport:=true,
org.apache.mina.filter*;version=${project.version};-noimport:=true,
org.apache.mina.handler*;version=${project.version};-noimport:=true,
org.apache.mina.proxy*;version=${project.version};-noimport:=true,
org.apache.mina.transport*;version=${project.version};-noimport:=true,
org.apache.mina.util*;version=${project.version};-noimport:=true
</Export-Package>

> 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

> One way to approach this problem is changing the pom.xml so:
> {code}
> ...
> <Private-Package>
> org.apache.mina.core.polling
> </Private-Package>
> ...
> {code}
