---------------------------------------

             Summary: Aries ResolveContext.insertHostedCapability() calls unsupported add()
method on capabilies
                 Key: ARIES-1439
                 URL: https://issues.apache.org/jira/browse/ARIES-1439
             Project: Aries
          Issue Type: Bug
          Components: Subsystem
    Affects Versions: subsystem-core-2.0.4
            Reporter: David Bosschaert
            Assignee: David Bosschaert
             Fix For: subsystem-2.0.6


The method {code}org.apache.aries.subsystem.core.internal.ResolveContext.insertHostedCapability(List<Capability>
capabilities, HostedCapability hostedCapability){code}
calls {{capabilities.add(hostedCapability)}}.

However the key reason for this callback is to insert this capability at the correct position
in the capabilities list. The Felix implementation of the List provided insist on a call to
{{add(idx, capability)}} which seems to make sense in this context. 

Currently this call causes the following exception:

{code}java.lang.UnsupportedOperationException: null
	at org.apache.felix.resolver.util.CopyOnWriteList.add(CopyOnWriteList.java:135)
	at org.apache.aries.subsystem.core.internal.ResolveContext.insertHostedCapability(ResolveContext.java:101)
	at org.apache.felix.resolver.Candidates.prepare(Candidates.java:934)
	at org.apache.felix.resolver.ResolverImpl.resolve(ResolverImpl.java:232)
	at org.apache.felix.resolver.ResolverImpl.resolve(ResolverImpl.java:158)
	at org.apache.aries.subsystem.core.internal.SubsystemResource.computeDependencies(SubsystemResource.java:372){code}
