How reproducible:


Steps to Reproduce:
1. Take a JDG Server 6.1, configure basic auth by going to jboss-datagrid-server-6.1.0/bin/add-user.sh and choosing option b), accept the proposed realm, and put role as REST.

2. Use the attached clustered.xml config which contains a JDBCStringBasedStore

3. Start a test oracle database: 

docker run --name oracle -d -p 49160:22 -p 49161:1521 -e ORACLE_ALLOW_REMOTE=true wnameless/oracle-xe-11g

4. Configure the server. Download the oracle driver ojdbc6.jar, the module.xml (attached) and clustered.xml (attached) and place the files in the right place:

mkdir -p jboss-datagrid-server-6.1.0/modules/com/oracle/jdbc/driver/main/
cp module.xml jboss-datagrid-server-6.1.0/modules/com/oracle/jdbc/driver/main/
cp ojdbc6.jar jboss-datagrid-server-6.1.0/modules/com/oracle/jdbc/driver/main/
cp clustered.xml jboss-datagrid-server-6.1.0/standalone/configuration/

5. Start the server

jboss-datagrid-server-6.1.0/bin/standalone.sh -c clustered.xml

6. Put a single key/value via Rest: 

curl -X PUT --user user:pass -H "Content-Type: text/plain" --data "value" http://localhost:8080/rest/mycache/key

4. Run the JDBCUpgradeTool with the attached conf.properties:

java -cp infinispan-jdbc-migrator52x-6.4.0.Final-redhat-4.jar:jboss-transaction-api_1.1_spec-1.0.1.Final-redhat-2.jar:ojdbc6.jar org.infinispan.persistence.migrator.jdbc.JdbcUpgradeTool conf.properties

Actual results:

Exception thrown:
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
	at org.jboss.marshalling.river.RiverUnmarshaller.doReadClassDescriptor(RiverUnmarshaller.java:955)
	at org.jboss.marshalling.river.RiverUnmarshaller.doReadNewObject(RiverUnmarshaller.java:1255)

Expected results:

Migration of a single key to a different table
