JDBC Object Store problem with Mariadb55 ---------------------------------------- Key: WFLY-5501 URL: https://issues.jboss.org/browse/WFLY-5501 Project: WildFly Issue Type: Bug Components: Transactions Reporter: Hayk Hovsepyan Assignee: Tom Jenkinson Fix For: 10.0.0.CR4 Attachments: mariadb_jar.zip, server.log, standalone.xml When configuring transactions to use Mariadb55 Datasource as a JDBC Object store, server fails to start with error: {code} 13:56:51,485 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("add") failed - address: ([("subsystem" => "transactions")]) - failure description: {"WFLYCTL0080: Failed services" => {"jboss.txn.ArjunaRecoveryManager" => "org.jboss.msc.service.StartException in service jboss.txn.ArjunaRecoveryManager: WFLYTX0005: Recovery manager create failed Caused by: java.lang.NullPointerException"}} {code} Steps to reproduce: 1. Create Mariadb55 JDBC driver module. Module archived directory is attached. 2. Add driver into configuration xml. 3. Create Datasource pointing to Mariadb55 database and using driver configured a a module. 4. Configure transactions to use jdbc-store the added Datasource. standalone.xml is attached. 5. Server fails to start. server.log is attached. config xml file part: {code} <subsystem xmlns="urn:jboss:domain:datasources:4.0"> <datasources> <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true"> <connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE</connection-url> <driver>h2</driver> <security> <user-name>sa</user-name> <password>sa</password> </security> </datasource> <datasource jta="false" jndi-name="java:jboss/datasources/jdbc-store" pool-name="JDBCObjectStore" enabled="true" use-java-context="true"> <connection-url>jdbc:mariadb://db22.mw.lab.eng.bos.redhat.com:3306/dballo17</connection-url> <driver>module_mariadb.jar</driver> <security> <user-name>dballo17</user-name> <password>dballo17</password> </security> </datasource> <drivers> <driver name="h2" module="com.h2database.h2"> <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class> </driver> <driver name="module_mariadb.jar" module="mariadb_jar"/> </drivers> </datasources> </subsystem> <subsystem xmlns="urn:jboss:domain:transactions:3.0"> <core-environment> <process-id> <uuid/> </process-id> </core-environment> <recovery-environment socket-binding="txn-recovery-environment" status-socket-binding="txn-status-manager"/> <coordinator-environment enable-tsm-status="true"/> <jdbc-store datasource-jndi-name="java:jboss/datasources/jdbc-store"/> </subsystem> {code} Attached necessary info: 1. server.log 2. Module zip to extract in $JBOSS_HOME/modules/system/layers/base 3. standalone.xml Notes: The same steps works for other databases. When step 4. is not executed server starts successfully, so module is recognized.
