Hi,
You really shouldn't install multiple bundles with same package and
same version, otherwise you'll encounter the well-known split-package
issue in OSGi container.

Hello,
Got a problem about Packages Exported by Multiple Bundles. There are
2 bundles exported org.apache.derby.jdbc package.
karaf@trun>install –s mvn:org.apache.servicemix.bundles/
org.apache.servicemix.bundles.derbynet/10.8.1.2_1
karaf@trun>install -s mvn:org.apache.derby/derbyclient/10.8.1.2
karaf@trun> list
[ 222] [Active ] [ ] [ ] [ 60] Apache
ServiceMix :: Bundles :: derbynet (10.8.1.2_1)
[ 238] [Active ] [ ] [ ] [ 60] Apache Derby
10.8 (10.8.1000002.1095077)
karaf@trun> exports | grep derby.jdbc
222 org.apache.derby.jdbc; version="10.8.1.2"
238 org.apache.derby.jdbc; version="0.0.0"
Then, install a bundle with Import-Package like this:
Import-Package:
javax.sql,org.apache.derby.jdbc,org.osgi.service.bluepri
nt;version="[1.0.0,2.0.0)",org.osgi.service.cm;version="[1.3,2)"
will throw a ClassNotFoundException:

If uninstall bundle 222, then, the app bundle will be installed
successful.
How to process this kind of problem of package exported from multi
bundles within karaf?
Thanks.
