-----------------------------------------------------------------

I add just two cents on the "issue" sharing my experience on another corner-case... (sadly) Java serialization.
I was able to use the documented work-around, I've a spring-devtools.properties with:


{noformat}
restart.include.drools-core=/drools-core-7.0.0.Final.jar
restart.include.drools-compiler=/drools-compiler-7.0.0.Final.jar
restart.include.kie-api=/kie-api-7.0.0.Final.jar
restart.include.kie-ci=/kie-ci-7.0.0.Final.jar
restart.include.kie-internal=/kie-internal-7.0.0.Final.jar
{noformat}

But in a rule using java serialization, I got an amazing:

{noformat}
Caused by: java.lang.ClassCastException: com.example.OrderREO cannot be cast to com.example.OrderREO
	at rules.com.example.CloneWithServiceCode.cloneWithServiceCode(CloneWithServiceCode.java:55) ~[na:na]
	at rules.com.example.Rule_My_Rule_621849765706.defaultConsequence(My_Rule_621849765706.java:9) ~[na:na]
	at rules.com.example.Rule_My_Rule_621849765706DefaultConsequenceInvokerGenerated.evaluate(Unknown Source) ~[na:na]
	at rules.com.example.Rule_My_Rule_621849765706DefaultConsequenceInvoker.evaluate(Unknown Source) ~[na:na]
	at org.drools.core.phreak.RuleExecutor.innerFireActivation(RuleExecutor.java:431) ~[drools-core-7.0.0.Final.jar:7.0.0.Final]
	... 129 common frames omitted
{noformat}

Given that I'll have to wipe-out every form of Java Serialization from the rules... (the Object.clone() was so tempting for our business-rules team... and they didn't knows the drawbacks) I would like to know if I missed to specify some jar in the spring-devtools.properties.

Thank's in advance.
