> In my application, i have rules that used org.joda.time.LocalDate to compare date like
> {noformat} 
> rule "toto"
> 	when
> 		LocalDateForDroolsTestBean(
> 			infDate>=supDate
> 		)
> 	then
> 		//Anything
> end
> {noformat} 
> With Drools 5.3, all works fine.
> With Drools 5.5, an exception occured because JIT optimizer automaticaly enabled:
> {noformat} 
> Exception in thread "main" java.lang.NoSuchMethodError: org.joda.time.LocalDate.compareTo(Lorg/joda/time/LocalDate;)I

> After search, it seems that the bytecode generated by org.drools.rule.builder.dialect.asm.ClassGenerator can't call the method  public int compareTo(Object partial) of org.joda.time.LocalDate. The parameter of the method must be the same class of the current object.
