Description

After our switch of the postgres-jdbc-driver from version 9.4-1201 to 42.1.3 the JDBCPersistenceAdapter does not recognize postgres any more.
The log:

new driver

old driver

2017-07-31 19:37:21,021 [INFO ] 11b-e48-c83 [JDBCPersistenceAdapter : loadAdapter] - Database adapter driver override recognized for : [postgresql_native_driver] - adapter: class org.apache.activemq.store.jdbc.adapter.PostgresqlJDBCAdapter

The cause is the change of the name from "postgres_native_driver" to "postgres_jdbc_driver" (getDriverName() now returns "PostgreSQL JDBC Driver"). The PostgresqlJDBCAdapter uses the name to find the class.
Our workaround is to add a file "postgres_jdbc_driver" to "META-INF/services/org/apache/activemq/store/jdbc" in the "activemq-jdbc-store-5.15.0.jar".
