Brugger Antony commented on JBRULES-759:
----------------------------------------

I have a case where this issue is not solved with JBoss Rules 3.0.5.

If I have a rule like this one in my DRL file:

rule "Search_date_1"
	when
		folder : InvalidityDossier(proposedEndInvalidityDate == null, endInvalidityDate == null, passageInvalidityDate > (new DateTime()))
	then
		folder.setSearchDate(folder.getDueDate());
		System.out.println("Search_date_1");
end

[InvalidityDossier is a Java Bean class with getter and setter for proposedEndInvalidityDate, endInvalidityDate, passageInvalidityDate and searchDate attributes]

The following exception occurs on the second call to addPackage on ruleBase (ruleBase.addPackage(pkg);):

java.lang.NullPointerException
	at be.gfdi.proto.drl.Rule_Search_date_1_0ReturnValue0Invoker.getMethodBytecode(Rule_Search_date_1_0ReturnValue0Invoker.java:32)
	at be.gfdi.proto.drl.Rule_Search_date_1_0ReturnValue0Invoker.equals(Rule_Search_date_1_0ReturnValue0Invoker.java:61)

	at be.gfdi.proto.rule.test.JbrulesTest.main(JbrulesTest.java:37)

If I remove this rule there is no exception (of course there are other rules in the DRL file)
