Re: [eclipselink-dev] EntityManagerJUnitTestSuite.testLockWithJoinedInheritanceStrategy: NPE

Hi Adrian,

  It looks like driverName is null in the call:

driver = (Driver)Class.forName(driverName, true, Thread.currentThread().getContextClassLoader()).newInstance();

Driver name should come from a file called test.properties. There are test.properties files in <base>/jpa/eclipselink.jpa.test and <base>/foundation/eclipselink.core.test. Depending on whether you are running the jpa tests or the core tests, those files will be used to get the driver name. To override those files, put a file called test.properties in your <user-home> directory and override any settings you need to override.
