Richard S. Hall commented on FELIX-3652:
----------------------------------------
If you can get me to reproduce it, then I can look into directly.
> ArrayIndexOutOfBoundsException when trying to adapt() a stopped bundle
> ----------------------------------------------------------------------
>
> Key: FELIX-3652
> URL: https://issues.apache.org/jira/browse/FELIX-3652
> Project: Felix
> Issue Type: Bug
> Components: Framework
> Affects Versions: framework-4.0.2
> Reporter: Dan Gravell
> Priority: Minor
>
> I have the following code block:
> final Iterable<Bundle> startedBundles = [...]
> for (Bundle bundle : startedBundles) {
> try {
> if(!FelixObrUtils.isFragment(bundle))
> sysBundle.getBundleContext().getBundle(bundle.getBundleId()).stop();
> } catch (BundleException e) {
> LOG.error("Failed to stop " + bundle.getSymbolicName(), e);
> }
> }
> resolver.deploy(0);
> blockingRefreshBundles(null, sysBundle.getBundleContext());
> for (Bundle bundle : startedBundles) {
> try {
> if(!FelixObrUtils.isFragment(bundle))
> sysBundle.getBundleContext().getBundle(bundle.getBundleId()).start();
> } catch (BundleException e) {
> LOG.error("Failed to restart " + bundle.getSymbolicName(), e);
> }
> }
> blockingRefreshBundles() blocks until frameworkWiring.refreshBundles has
> completed using a CountDownLatch and a FrameworkListener.
> Pertinently, FelixObrUtils.isFragment looks like:
> public static boolean isFragment(Bundle bundle) {
> return (bundle.adapt(BundleRevision.class).getTypes() &
> BundleRevision.TYPE_FRAGMENT) != 0;
> }
> Upon the second call to FelixObrUtils.isFragment I get:
> java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
> at java.util.ArrayList.rangeCheck(ArrayList.java:571)
> at java.util.ArrayList.get(ArrayList.java:349)
> at org.apache.felix.framework.BundleImpl.adapt(BundleImpl.java:1046)
> at
> com.elsten.bliss.updater.FelixObrUtils.isFragment(FelixObrUtils.java:149)
> at
> com.elsten.bliss.updater.OnlineUpdater$2.doRun(OnlineUpdater.java:124)
> at
> com.elsten.util.CatchThrowableRunnable.run(CatchThrowableRunnable.java:23)
> at
> java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110)
> at
> java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603)
> at java.lang.Thread.run(Thread.java:679)
> Presumably this is because the bundle has been stopped, possibly updated and
> refreshed in the meantime.
> Maybe I should not be doing this on a stopped bundle, and I should be getting
> a fresh view of the bundle, but shouldn't this be handled differently? AIOOBE
> is not documented as an exception that may be thrown in the OSGi API. Knowing
> how to handle this requires knowledge of BundleImpl's implementation
> (m_revisions etc).
