Description Christoph Laeubrich

2011-07-03 15:47:41 EDT

Build Identifier: 3.6.0.v20100517

When adding a new Class to a bundle and then update it through Bundle.update(URL) leads to a ClassNotFound Exception (see stacktrace 1 below). Sometimes the same apply when adding a method to an interface leads to a MethodNotFound (see stacktrace 2 below).

The problem can be fixed by caling the framework with the -clean option, so it seems that there is somewhere a stale reference or caching of classloading information

Reproducible: Sometimes

Steps to Reproduce:
Step I:
1. Create a bundle which defines a service interface
2. Create a bundle providing the service and implementing the service
3. Create a bundle using the service and calling the methods (I always use DS for that)
4. Start the Framework --> Everything should work

Step II:
1. Add a new class  to the implementation (only needed internal) or add a new method to the service interface
2. Increment the version to allow updating
3. Use it in the implementation bundle
4. export the bundles to a (local) webserver or something

Step III:
1. start the framework and update the bundles via the Bundle.update(URL)
2. --> Exceptions should occur

Step IV:
1. restart framework
2. --> Problem still present

Step V:
1. Restart the framework with the -clean option
2. --> No more problems

Could you please attach the bundles you used in your testcase?

Comment 2 Christoph Laeubrich

Since  I can't reproduce the problem anymore, maybe it was related to a package-refresh not taking place or something.
