[eclipselink-users] Derby & addStructConverters fails with NPE 
Using Derby as a database driver I get the following error:
[EL Config]: 2009.04.07 23:47:39.500--ServerSession(30266940)--Connection(6606816)--Thread(Thread[ModalContext,6,main])--connecting(DatabaseLogin( 
	platform=>DerbyPlatform

datasource URL=> "jdbc:derby:C:/DerbyDatabases/hellojpa-database8;create=true" 
))

    </properties>

What can it mean? Same error I get when using H2/HSQL as the driver.

Thanks,
Phil
