PerProcessInstanceRuntimeManager creation fails at startup

I have created a web project based on jBPM 6.1.0-SNAPSHOT codes from github. While creating perprocessinstanceruntimemanager at startup I see the below error. I am using MySql db.

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'bigint)=processins1_.InstanceId and contextmap0_.OWNER_ID='default-per-pinstance' at line 1

The stack trace is

The error is coming from this new NamedQuery in org.jbpm.runtime.manager.impl.jpa.ContextMappingInfo.java

@NamedQuery(name="FindKSessionToInit",
query="select cmInfo.ksessionId from ContextMappingInfo cmInfo, "
+ "ProcessInstanceInfo processInstanceInfo join processInstanceInfo.eventTypes eventTypes"
+ " where eventTypes = 'timer' and cast(cmInfo.contextId as long) = processInstanceInfo.processInstanceId"
+ " and cmInfo.ownerId = :ownerId")})

Casting of contextId to long is failing in MySql.
