Amichai Rothman commented on DOSGI-51:
--------------------------------------
I just hit this issue as well. I'm not sure what resolution 'Later' means on a
closed bug - will anyone ever look at it again if it is closed? In any case I
think it should be re-opened, since it's still there 4 years later (I'm on JDK
7u45, DOSGi 1.6-SNAPSHOT). In my case the workaround of specifying the impl
class in the method signature won't work, since there is more than one
implementation for the interface, which is pretty much the point of using
interfaces. Is there any other known workaround or solution?

> Key: DOSGI-51
> URL: https://issues.apache.org/jira/browse/DOSGI-51
> Project: CXF Distributed OSGi
> Issue Type: Bug
> Affects Versions: 1.0, 1.1
> Environment: OS: Linux Debian Lenny
> Java: Sun JDK 1.6.0 Update 13
> OSGi: Equinox 3.5.0.v20090520
> CXF/DOSGi: Single Bundle Distribution 1.0/1.1.SNAPSHOT
> Reporter: Saul Goode

> I've got a Service PassObject exposed by CXF/DOSGi running on the server.
> This service contains a method passAnObject which receives an object of type
> MathHelper. MathHelper is an interface known both to the server and client.
> The method passAnObject calls the methods MathHelper.getName() and
> MathHelper.isGreaterThanZero(int) on the received object. When the client
> calls the method passAnObject and passes an object which implements
> MathHelper the following happens: The call to getName works as expected and
> returns a String. But the call to the other method raises an exception on the
> server (stack trace appended). I have this problem with both 1.0 and the
> 1.1.SNAPSHOT.
> Is it unsupported to pass objects to a remote service provider? Or is this
> some kind of bug?
> I didn't find an option to upload sth, so I uploaded the sample code to:
> http://ul.to/4vlftz
> The archive contains the server, client and interface bundles. The interface
> bundle runs on both the server and client.
