Bundle Fragments not resolved correctly
---------------------------------------
Key: FELIX-1197
URL: https://issues.apache.org/jira/browse/FELIX-1197
Project: Felix
Issue Type: Bug
Components: Framework
Affects Versions: felix-1.8.0
Reporter: Sergio Mestre
Hi all,
I have the following behaviour, if I try to attach more than one bundle
fragment to the same bundle host.
java.lang.ClassCastException:
org.apache.felix.framework.searchpolicy.ModuleImpl cannot be cast to
[Ljava.lang.Object;
at
org.apache.felix.framework.FelixResolverState.checkForConflicts(FelixResolverState.java:220)
ERROR: Error starting file:bundle/org.apache.felix.shell.jar
(org.osgi.framework.BundleException: Unresolved constraint in bundle 31: Unable
to merge fragments)

The bundle fragments have been tested separately and they work as they should.
( e.g. Frag A => Host A => O.K.
Frag B => Host A => O.K.
)
If I try to resolve both bundle fragments than i get the exception above. I
took a look at the source and it seems to me that there is a bug in the
FelixResolverState class. Inside the method checkForConflicts(IModule host,
List fragmentList) there is a map definition Map ipMerged = new HashMap();
where the key is a String and the Value a Object[] .
Later on in a for loop the same map is used to store keys from type String and
values from type ModuleImpl. This causes a the above classcast exception in the
line 220.
Do I have any mistakes in my bundle fragment headers or is this realy a bug ?
Best regards
Sergio
