EHCache CacheManager with RMI Clustering does not start in Fuse
Issue
- EHCache functionality is included in Fuse:
Apache ServiceMix :: Bundles :: ehcache (192)
---------------------------------------------
...
Bundle-Name = Apache ServiceMix :: Bundles :: ehcache
Bundle-Description = This OSGi bundle wraps ehcache 2.5.1 jar file.
Bundle-SymbolicName = org.apache.servicemix.bundles.ehcache
Bundle-Version = 2.5.1.1
And it works fine in a non-clustered environment. However when we enable RMI replication, the bundle fails to start.
- The offending class does exist in the classpath:
JBossFuse:karaf@root> list -t 1 | grep ehcache
[ 192] [Active ] [ ] [ ] [ 40] Apache ServiceMix :: Bundles :: ehcache (2.5.1.1)
JBossFuse:karaf@root> classes 192 | grep RMICachePeer_Stub
You are about to access system bundle 192. Do you wish to continue (yes/no): yes
net/sf/ehcache/distribution/RMICachePeer_Stub.class
JBossFuse:karaf@root> headers 192 | grep net.sf.ehcache.distribution

This issue is specific to Fuse as EHCache RMI clustering works outside Fuse runtime. Also this has been tested on an actual cluster, with the correct rmiUrls supplied to each node, with identical unsuccessful results.
