java ee - Openjpa slice with spring issue -

i have been trying configure openjpa-slice spring boot. configuration shared follows:

@configuration public class datasourceconfiguration extends jpabaseconfiguration{  @bean(name = "slice1") public datasource datasource() {     jndidatasourcelookup datasourcelookup = new jndidatasourcelookup();     datasource datasource = datasourcelookup.getdatasource("java:/mysqlxads");     return datasource; }  @bean(name = "slice2") public datasource datasource2() {     jndidatasourcelookup datasourcelookup = new jndidatasourcelookup();     datasource datasource = datasourcelookup.getdatasource("java:/mysqlxads2");     return datasource; }  @override protected map<string, object> getvendorproperties() {     hashmap<string, object> map = new hashmap<string, object>();     return map; }  public localcontainerentitymanagerfactorybean entitymanagerfactory(         entitymanagerfactorybuilder builder) {     map<string, object> properties = new hashmap<string, object>();      properties.put("openjpa.brokerfactory", "slice");     properties.put("openjpa.slice.names", "one, two");     properties.put("openjpa.slice.master", "two");     properties.put("openjpa.slice.lenient", "false");     properties.put("openjpa.slice.connectiondrivername", "com.mysql.jdbc.driver");     properties.put("openjpa.slice.one.connectionfactoryname", "java:/mysqlxads");     properties.put("openjpa.slice.two.connectionfactoryname", "java:/mysqlxads2");     properties.put("openjpa.slice.distributionpolicy", "com.services.sample.configuration.userdistributionpolicy");     properties.put("openjpa.slice.transactionpolicy" , "xa");     properties.put("openjpa.transactionmode" , "managed");     properties.put("openjpa.connectionfactorymode", "managed");     properties.put("openjpa.jdbc.dbdictionary", "mysql");     properties.put("openjpa.log","defaultlevel=warn, runtime=info, tool=info, sql=trace");      return builder             .datasource(datasource()).jta(true)             .properties(properties)             .packages("com.services.sample.domain.entity")             .persistenceunit("sample")             .build(); }  @override protected abstractjpavendoradapter createjpavendoradapter() {     openjpavendoradapter jpavendoradapter = new openjpavendoradapter();     jpavendoradapter.setshowsql(true);     return jpavendoradapter; }  public platformtransactionmanager transactionmanager(@qualifier("entitymanagerfactory")entitymanagerfactory entitymanagerfactory){     jtatransactionmanager transactionmanager = new jtatransactionmanager();     return transactionmanager; } 

}

persistence.xml

<persistence-unit name="sample" transaction-type="jta" >     <description>generated-persistence-unit</description>     <provider>org.apache.openjpa.persistence.persistenceproviderimpl</provider>     <class> ... </class>  </persistence-unit> 

i have configured wildfly server 10. both xa-datasources point different databases. however, when application boots , execute query fetches data datasource passed builder twice. seems have wrong slice configuration. not sure whats problem in case.
