             Summary: ClassCastException if cache.keyset() is invoked for a string-keyed-jdbc-store in C/S mode
                 Key: ISPN-4125
                 URL: https://issues.jboss.org/browse/ISPN-4125
             Project: Infinispan
          Issue Type: Bug
            Reporter: Wolf-Dieter Fink
            Assignee: Mircea Markus


If the cache is empty cache.keyset() invocation returns an empty set.
If it is invoked after entities are added it failes with the Exception below.
The same test work if a binary-keyed-jdbc-store is used!

The HotRod client is based on the hot-rod C/S quickstart.

The configuration is:
        <subsystem xmlns="urn:infinispan:server:core:6.0" default-cache-container="clustered">
            <cache-container name="clustered" default-cache="string" statistics="true">
                <transport executor="infinispan-transport" lock-timeout="60000"/>


                <replicated-cache name="string" mode="ASYNC" start="EAGER">
                    <locking isolation="READ_COMMITTED" acquire-timeout="20000" concurrency-level="500" striping="false"/>
                    <transaction mode="NONE"/>
                    <string-keyed-jdbc-store datasource="java:jboss/datasources/JDGDatasource" passivation="false" preload="true" purge="false" shared="false">
                        <!-- property name="databaseType">ORACLE</property -->
                        <string-keyed-table prefix="qs">
                            <id-column name="id" type="VARCHAR(255)"/>
                            <data-column name="datum" type="BLOB(2000)"/>
                            <timestamp-column name="version" type="BIGINT"/>
                        </string-keyed-table>
                        <write-behind modification-queue-size="1024" shutdown-timeout="25000" flush-lock-timeout="15000" thread-pool-size="5" />
                    </string-keyed-jdbc-store>
                    <expiration interval="10000" />
                </replicated-cache>
