Summary: UnsupportedOperationException when embedding felix in
WebSphere
Key: FELIX-5131
URL: https://issues.apache.org/jira/browse/FELIX-5131
Project: Felix
Issue Type: Bug
Components: Framework, Resolver
Affects Versions: resolver-1.6.0, framework-5.2.0
Reporter: Thomas Schurins
Hello, we are embedding the OSGi framework in our application (creating the
framework , managing its export packages, contolling the bundles &c.). This
works great in a lot of enviroments, but not on WebSphere (using the IBM JDK):

The problem seems to be that in the IBM JDK, the Collections.binarySearch
method directly uses the listIterator of the list if it is not a RandomAccess
list (while the oracle JDK doesn't).
A solution it to add the interface RandomAccess to the CopyOnWriteList class.
I've tested this locally and eveything runs fine.
