Ramesh Reddy commented on TEIID-1439:
-------------------------------------
This error only occurs in the cluster profiles like "all". Teiid uses a
Expiration based JBoss Cache in clustered mode. To make the expiration work, the JBoss
Cache needs a data element called "expiration" stored along with the cache and
its value as separate entity on the same node. However, when the keys are read back from
cache all the keys were assumed to be "cache" keys and not taking the
"expiration" key which is string based key into account. Thus when the client
code using the cache type casts the key to a CacheID the server throws a
ClassCastException.
Workaround is Turn OFF result caching in the "server". This will avoid the
caching layer be used at all.
Adminshell/API - sequence of datasource creation/VDB deployment and
queries results in deployment error
