Description

When the cachemanager is shut down, cache event listeners are deregistered. It lools like during deregistration of the cachelisteners a java.lang.UnsupportedOperationException is thrown. This is happening because the remove() method of the COWIterator of the CopyOnWriteArrayList class is not supported!

Note: Is exception occurs also if the net.sf.ehcache.event.RegisteredEventListeners.unregisterListener is invoked directly:

java.lang.UnsupportedOperationException at java.util.concurrent.CopyOnWriteArrayList$COWIterator.remove(CopyOnWriteArrayList.java:1004) at net.sf.ehcache.event.RegisteredEventListeners.unregisterListener(RegisteredEventListeners.java:247) at ch.deltaenergy.collections.AbstractCollection$CacheExpiryListener.dispose(AbstractCollection.java:511) at net.sf.ehcache.event.RegisteredEventListeners.dispose(RegisteredEventListeners.java:275) at net.sf.ehcache.Cache.dispose(Cache.java:2085) at net.sf.ehcache.CacheManager.shutdown(CacheManager.java:1033)

Is this the same issue as https://jira.terracotta.org/jira//browse/EHC-653

Yep, this is the same issue as EHC-653. I guess we can close this issue. Any idea when the release date of Ehcache 2.0.1 is?

Snapshots are there to try (or they will be in 24 hours). probably will be released in 2.5 weeks officially.

Dup of EHC-653
