[rules-users] Is Drools 5.1 backward compatible with 5.0.1?

[Tan Hui Onn]

Are the test cases failed because of
java.lang.NullPointerException
	at org.drools.command.runtime.BatchExecutionCommand.execute(BatchExecutionCommand.java:142)
	at org.drools.command.runtime.BatchExecutionCommand.execute(BatchExecutionCommand.java:1)
	at org.drools.impl.StatelessKnowledgeSessionImpl.execute(StatelessKnowledgeSessionImpl.java:239)
	at droolsbook.bank.service.impl.ValidationTest.assertReportContains(ValidationTest.java:97)
	at droolsbook.bank.service.impl.ValidationTest.studentAccountCustomerAgeLessThan(ValidationTest.java:219)
	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

	at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
	at java.lang.reflect.Method.invoke(Method.java:597)
	......
?
	
I checked the source of CommandFactoryProviderImpl (5.1.0.CR1) and found this
	public Command newInsertElements(Iterable objects) {
//		TODO: FIX THIS
//		return new InsertElementsCommand(objects);
		return null;
	}

But it has been fixed in 5.1 FINAL.
