I try to use tminglei / slick-pg v9.0.0 with slick 3.0.0 and get an IllegalAccessException :
akka.actor.ActorInitializationException: exception during creation at akka.actor.ActorInitializationException$.apply(Actor.scala:166) ~[akka-actor_2.11-2.3.11.jar:na] ...

HikariCP is the default connection pool in slick 3.0.0
I defined the driver class as in example :
trait MyPostgresDriver extends ExPostgresDriver with PgArraySupport with PgEnumSupport with PgRangeSupport with PgHStoreSupport with PgSearchSupport{ override val api = new MyAPI {} ////// trait MyAPI extends API with ArrayImplicits with RangeImplicits with HStoreImplicits with SearchImplicits with SearchAssistants } object MyPostgresDriver extends MyPostgresDriver
My database configuration is pretty simple [excerpt from configafe file follows]:
slick.dbs.default { driver="com.github.tminglei.MyPostgresDriver$" db { driver="org.postgresql.Driver" url="jdbc:postgresql://hostname:port/dbname" user=user password="pass" } }
It doesn't seem like it should work, and yet ...
Should I somehow change the driver class? Is this something else?
Note: as seen from stacktrace, I use
- Java 1.7.0_79
- Scala 2.11.7
- akka 2.3.11 (I use the config instance for slick and akka)
- slick 3.0.0
- HikariCP-java6 2.3.8
- tminglei slick-pg_core 0.9.0
Finally, when debugging through jdk code in Class.class (decompiled line 143)
Constructor tmpConstructor1 = this.cachedConstructor;
I get the following (toString'ed) value (as shown by intellij):
private com.github.tminglei.MyPostgresDriver$()
Could this be an indicator of the problem? If so, how can I fix it?
EDIT
I replaced the custom driver configuration with a PostgresDriver stock as follows:
slick.dbs.default { driver="slick.driver.PostgresDriver$" db { driver="org.postgresql.Driver" url="jdbc:postgresql://hostname:port/dbname" user=user password="pass" } }
The error is the same:
akka.actor.ActorInitializationException: exception during creation ... Caused by: java.lang.RuntimeException: driverClassName specified class 'slick.driver.PostgresDriver$' could not be loaded ... Caused by: java.lang.IllegalAccessException: Class com.zaxxer.hikari.AbstractHikariConfig can not access a member of class slick.driver.PostgresDriver$ with modifiers "private"
