             Summary: Operators on java.lang.Comparable object doesn't work if JIT is enable
                 Key: DROOLS-37
                 URL: https://issues.jboss.org/browse/DROOLS-37
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 5.5
         Environment: Windows XP
Java 1.5
joda-time 1.6.2
            Reporter: Jérémy SOULA
            Assignee: Mark Proctor


In my application, i have rules that used org.joda.time.LocalDate to compare date like infDate>=supDate.

With Drools 5.3, all works fine.

With Drools 5.5, an exception occured when JIT optimizer is enabled:
Exception in thread "main" java.lang.NoSuchMethodError: org.joda.time.LocalDate.compareTo(Lorg/joda/time/LocalDate;)I
	at ConditionEvaluatorf8ba8fa3003345adbf3979e901488f23.evaluate(Unknown Source)

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.
