Description Martin Petzold

2011-01-10 06:06:14 EST

Environment: JmDNS, R-OSGi

Provider and Consumer Application (OSGi instance) on the same machine. If I close a provider and then reopen it (short time after each other) this exception occured.

Can you provide a test case that reproduces this behavior?

I think this problem only occurs if a remote service is registered before r-osgi is completely started (e.g. set start levels).
