DB2 to Neo4j using ETL tool error, Exception in thread "main" java.lang.AbstractMethodError: com.ibm.db2.jcc.t4.b.getSchema()Ljava/lang/String

Neo4j Graph Platform ETL-Tool
1

Neo4j Desktop 4.0.8
Neo4j ETL 1.4.2
DB2 v10.1

I'm trying to connect and import a DB2 table present in Mainframe platform using jdbc drivers.
I have used the appropriate JDBC driver jar files and the license authentication jar file.
I have given correct host name, portnumber, Database name, Schema name and Mainframe credentials.

When i;m trying to test and save connection, i'm getting the following error.

Exception in thread "main" java.lang.AbstractMethodError: com.ibm.db2.jcc.t4.b.getSchema()Ljava/lang/String;
	at org.neo4j.etl.rdbms.Support.successMessage(Support.java:64)
	at org.neo4j.etl.rdbms.Support.testConnection(Support.java:33)
	at org.neo4j.etl.rdbms.Support.main(Support.java:74)

If i'm giving incorrect mainframe credentials it is showing that invalid userid/password. This means connections has been established and credential validations are done properly.

Please help me as why that error message is coming, what is the reason and where to fix for this error?

Thanks in advance!
