Branch 5.3.x has been created
by Geoffrey De Smet
If you want any commit to master also be available in 5.3.0.Final too,
make sure to cherry-pick it to the 5.3.x branch.
Note: there is no branch on jbpm as jbpm is not being released at this time.
Note: brms related changes must also be cherry-picked to the 5.2.x branch.

surveillance platform that allows clinicians to accurately detect risk
factors, and perform interventions. The platform leverages the
GigaSpaces implementation of Tuple-space and the Drools rule engine to
create a massively parallel expert system. This architecture allows for
customizable handling of millions of HL7 messages per day, evaluation of
thousands of clinician created business rules, and reasoning over
hundreds of thousands of patient data facts to provide near-real-time
surveillance.

*Medicare and Medicaid look to rules for the future of healthcare*
The Center for Medicare and Medicaid Services (CMS), an agency of the
Federal government, has aggressive plans to modernize healthcare
administrative systems and Electronic Healthcare Records (EHR).
The use of Rules and Business Process Management are a focal point for
the new systems. This session will describe how Medicare and Medicaid
work and how the government (Federal and State) is looking for Rules and
BPM to help change both the administrative and clinical environments.
This session will look at the Medicaid Information Technology
Architecture (MITA) and how Rules and BPM can augment this Service
Oriented Architecture. We will discuss how to get involved in some of
the many projects that are currently underway

Need help: DroolsStreamUtils.streamIn(InputStream) fails resolving declared data type in 5.2.0.Final+
by Ansgar Konermann
Hi,
While trying to get some integration tests of the Maven Drools Plugin
green when used with Drools 5.2.0.Final and 5.3.0.Beta1, I'm getting
weird behaviour of the newer Drools version when it comes to
deserializing KnowledgePackages.
What do I do in the code?
- compile three *.drl files (see below)
- serialize the resulting KnowledgePackages using
DroolsStreamUtils.streamOut(new FileOutputStream(outputFile),
knowledgeBuilder.getKnowledgePackages(), false) from within the plugin
(see [1], [2])
- de-serialize the knowledge packages using
DroolsStreamUtils.streamIn(new FileInputStream(file)) in a TestNG test
[3], using [4]
- I get java.lang.ClassNotFoundException for a declared data type:
java.lang.ClassNotFoundException: model.Age
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
at java.security.AccessController.doPrivileged(Native Method)

at
java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream.java:1574)
at java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1495)
Strangely enough, the same code works well if I switch to Drools 5.1.1.
What changed between 5.1.1 and 5.2.0.Final that might cause this effect?
Might I be doing something wrong using DroolsStreamUtils?
Would be happy about any hints.
Thank you in advance.
Here are the three input files, which get compiled exactly in this order:
1) Person.drl
package model;
declare Person
name: String
end
2) Age.drl
package model;
declare Age
person: Person
age: Integer
end
3) minimum-age.drl:
package rules;
dialect "mvel"
import model.Person;
import model.Age;
rule "check minimum age"
when
Age( $person: person, age < 18 )
then
insertLogical("TOO YOUNG: " + $person.name )
end
Best regards

https://issues.jboss.org/browse/JBRULES-2432
by Michael Anstis
This JIRA basically says it's a bug that Templates cannot be expanded unless
a value is given for each template-key.
E.G. Smurf( name == "@{smurfName}", colour=="@{smurfColour}" ) won't be
included in the generated DRL unless a value for "smurfName" and
"smurfColour" is given.
IMO, I'd agree - it's a painful limitation, however thought I'd ask if
anybody knows of any history as to why it might have been implemented this
way before I stamp over what might be considered as "correct behavior"?
Obviously, in my example, Smurfs are always blue ;)
Cheers,

Formal verification of Drools - master's thesis
by Jiri Svitak
Hello,
I work for Redhat as BRMS QE and I have to choose topic for my master's
(diploma) thesis. It would be convenient for me to combine my job and
the school thesis. I would like to know your opinions to following ideas:
1. Static analysis of Drools code with Findbugs. I have already talked
with Geoffrey and he said that you use Findbugs, but only for common
Findbugs scenarios. The thesis would then cover user defined bug
patterns for common bugs based on bug reports or your experience.
2. Model checking of Drools with JavaPathFinder. Model checking verifies
property of system by exploring state space of the system. The property
is described by CTL or LTL logic (general example: given a concurrent
program, we ask whether it is deadlock-free)
3. Different topic.
I would like to know your opinions and views if you would find that
useful. If you have some tips on features to verify, on common bugs
which could be found by these methods. Also if you'll be willing to
answer some questions about Drools source code if needed.
Thank you in advance.
Best regards
Jiri Svitak
