[rules-users] NoMuchMethod - But there is!

[Steven Waldren]

Hello,

I downloaded the JBoss Rules 4.0 Eclipse IDE.  I built a small  
project with about 120 rules. My test asserts around 500 objects.  
When I try to add one more rule (regardless of the content of the  
rule) I get the error below, stating no such method error.  Even if I  
add the following rule, I still get the error:

rule "new rule"
	when
		Object()
	then
		System.out.print("test");
end


What other problems can throw these errors?

Thanks,
Steven
