hi,
We are using Drools 4.0.7 in a web application deployed in WebSphere 6.1.
Occasionally, we have rule engine failure caused by RuntimeDroolsException
(whose root cause is shown as ClassCastException) when firing rules. Other
times, the rules are executing without errors. Here is the stack trace of
the exception. What are the possible reasons?
Thanks,

What are you guys doing with CGLIB? or is this WebSphere doing some
sneaky thing behind the scenes? Or is it SpringAOP doing sneaky things?
Caused by:
java.lang.ClassCastException: com.adesa.data.grounding.pojo.Inventory
incompatible with
com.adesa.data.grounding.pojo.Inventory$$EnhancerByCGLIB$$de81aab3
At compile time we determine that "inventory" is a
com.adesa.data.grounding.pojo.Inventory. If at runtime what arrives into the
expression is a
com.adesa.data.grounding.pojo.Inventory$$EnhancerByCGLIB$$de81aab3,
and it is not a proper subclass, you might get such problems.
Having said that, I will talk to Mike to check if this can be prevented
somehow, but I really don't know if it will be possible...

Edson,
We are not sure how the CGLIB proxy is getting created. We were under the
impression that it is the shadow fact proxy generated by Drools itself. I
would like to share a few more points about our application in case they are
somehow related to this problem.
1. We are using Spring AOP for intercepting method calls and passing the
facts, globals etc to a class that invoke Drools. Version of Spring is 2.0.7
2. We are using Hibernate 3.x/JPA for persistence. In fact the Inventory
POJO that is causing the ClassCastException is a JPA entity
3. We have rules defined in multiple packages. The Inventory POJO is used by
rules in all the packages. But the exception is occurring only for rules in
a particular package. That too only occasionally.
Please let me know if any other information is required.
Thanks,
Seema

Hi Seema,
Your rules look fine, and the reason you see an "eval" in the exception
text is that this:
inventory.leaseInformation != null
Is resolved as an eval.
Anyway, drools does *not* use CGLIB. We generate bytecode directly
using ASM. No CGLIB in the middle.
The problem, whatever it is, is related to the pojo model and any of
these frameworks interfering with it. So, if you can create an isolated test
case that allow us to reproduce the problem, it will help us understand how
can we support your scenario of usage.
Thanks,
Edson

Edson,
We are not sure how the CGLIB proxy is getting created. We were under the
impression that it is the shadow fact proxy generated by Drools itself. I
would like to share a few more points about our application in case they
are
somehow related to this problem.
1. We are using Spring AOP for intercepting method calls and passing the
facts, globals etc to a class that invoke Drools. Version of Spring is
2.0.7
2. We are using Hibernate 3.x/JPA for persistence. In fact the Inventory
POJO that is causing the ClassCastException is a JPA entity
3. We have rules defined in multiple packages. The Inventory POJO is used
by
rules in all the packages. But the exception is occurring only for rules in
a particular package. That too only occasionally.
Please let me know if any other information is required.
Thanks,
Seema

Edson,
Thanks for your reply. Reproducing the error looks difficult since it
happens only at times, but we will try. However, I noticed a bug reported in
your JIRA which also has reported a similar ClassCastException with a CGLIB
proxy.
https://jira.jboss.org/jira/browse/JBRULES-1784
It says that the bug has been fixed in version 5.0 of Drools. But it does
not mention the environment in which it was tested, so can't be sure if it
is related to our case.
Thanks,
Seema

hi Edson.
This is in continuation with the below issue that I had posted a few months
back. Even though we removed Spring AOP from the application then, the
problem still occurs at times. I was wondering if Hibernate was the culprit,
but fail to understand why it is not consistently happening.
The Inventory object which is causing the ClassCastException is a Hibernate
proxy since it is lazy loaded. The injected fact contains a reference to
this Inventory. So I was wondering if the issue has something to do with
shadow fact creation. When the shadow is created for a fact that contains a
Hibernate proxy, is there any possibility of this problem?
Thanks,
Seema

Hi Seema,
Your rules look fine, and the reason you see an "eval" in the
exception
text is that this:
inventory.leaseInformation != null
Is resolved as an eval.
Anyway, drools does *not* use CGLIB. We generate bytecode directly
using ASM. No CGLIB in the middle.
The problem, whatever it is, is related to the pojo model and any of
these frameworks interfering with it. So, if you can create an isolated
test
case that allow us to reproduce the problem, it will help us understand
how
can we support your scenario of usage.
Thanks,
Edson

FYI: Spring AOP enhances objects via CGLIB when no interface is available.
If an interface is avaiable, it uses an jdk dynamic proxy.

Subject: Re: [rules-users] ClassCastException when firing rules
Edson,
We are not sure how the CGLIB proxy is getting created. We were under the
impression that it is the shadow fact proxy generated by Drools itself. I
would like to share a few more points about our application in case they
are
somehow related to this problem.
1. We are using Spring AOP for intercepting method calls and passing the
facts, globals etc to a class that invoke Drools. Version of Spring is
2.0.7
2. We are using Hibernate 3.x/JPA for persistence. In fact the Inventory
POJO that is causing the ClassCastException is a JPA entity
3. We have rules defined in multiple packages. The Inventory POJO is used
by
rules in all the packages. But the exception is occurring only for rules
in
a particular package. That too only occasionally.
Please let me know if any other information is required.
Thanks,
Seema

Caused by:
java.lang.ClassCastException: com.adesa.data.grounding.pojo.Inventory
incompatible with
com.adesa.data.grounding.pojo.Inventory$$EnhancerByCGLIB$$de81aab3
At compile time we determine that "inventory" is a
com.adesa.data.grounding.pojo.Inventory. If at runtime what arrives into
the
expression is a
com.adesa.data.grounding.pojo.Inventory$$EnhancerByCGLIB$$de81aab3,
and it is not a proper subclass, you might get such problems.
Having said that, I will talk to Mike to check if this can be
prevented
somehow, but I really don't know if it will be possible...

Thanks Dean, we have removed the AOP implementation to check if that is the
source of the problem.
Edson, Is there any chance for a ClassCastException if the fact classes in
the application were changed, but the fact model classes that are part of
the compiled rule package were not updated to the most recent version? But
then it would cause exceptions consistently, right? In our case, the
exceptions are thrown occasionally only.
Thanks,
Seema

Yes, that is correct. If the underlying class interface changed, java
will raise CCE. Rulebase must be recompiled in that case.

Thanks Dean, we have removed the AOP implementation to check if that is the
source of the problem.
Edson, Is there any chance for a ClassCastException if the fact classes in
the application were changed, but the fact model classes that are part of
the compiled rule package were not updated to the most recent version? But
then it would cause exceptions consistently, right? In our case, the
exceptions are thrown occasionally only.
Thanks,
Seema
