IllegalArgumentException with bind method
Hi list,
I am struggling with a problem where I can't use a service within
another service. The exception is:
21.07.2011 11:59:11.254 *ERROR* [FelixStartLevel] com.etc.pp.core
[com.etc.pp.PostValidator] The bindValidationService method has thrown
an exception (java.lang.IllegalArgumentException: argument type
mismatch) java.lang.IllegalArgumentException: argument type mismatch

The service is referenced via a @Reference annotation on top of a
variable declaration.
And it is exported in another bundle with the @Service annotation. The
type of the variable and the service interface match.
The console shows that the service is available and that the component
that uses it has satisfied dependencies.
But why then there is a problem with the autogenerated bindmethod? I
guess it is a stupid error somewhere because I have used similar
service setups successfully.
However I have no idea how to further debug this one. Maybe anybody else?
Regards,
Markus

Re: IllegalArgumentException with bind method
Posted by Markus Joschko <ma...@gmail.com>.
OK, found it.
Both bundles contained the same package. The importing bundle had
marked this package as private while the service in the exporting
bundle was exactly in that package.
After I moved the service class to another (non "shared") package it works fine.
