[JBoss JIRA] (WFLY-5834) NPE handling request to /clusterbench/ejbservlet
by Radoslav Husar (JIRA)
[ https://issues.jboss.org/browse/WFLY-5834?page=com.atlassian.jira.plugin.... ]
Radoslav Husar reassigned WFLY-5834:
------------------------------------
Assignee: Radoslav Husar (was: Romain Pelisse)
Thanks for the second pair of eyes Romain! You are right about ternary operator on volatile being prone to still returning null -- both expressions are all evaluated independently. Needs a proper yet efficient synchronization. I ll take it from here, created ISPN-6122 and submitted pull request to infinispan.

[JBoss JIRA] (DROOLS-1044) KieBase 'includes' does not handle the inclusion of KieBases that use the same package-names correctly.

> KieBase 'includes' does not handle the inclusion of KieBases that use the same package-names correctly.
> I define 2 KJARs, each with a kmodule.xml that defines a KieBase. KJAR1 has a dependency on KJAR2 in its pom.xml.
> The KieBase defined in KJAR1 includes the KieBase defined in KJAR2.
> If the KieBases get their Drools Resources (e.g. .drl) from different packages (e.g. 'rules' and 'rules2', everything works fine, e.g.:
> KJAR1 kmodule.xml:
> {code:xml}
> <?xml version="1.0" encoding="UTF-8"?>
> <kmodule xmlns="http://jboss.org/kie/6.0.0/kmodule">
> <kbase name="kbase1" equalsBehavior="equality" default="true" packages="rules" includes="kbase2">
> <ksession name="ksession1" default="true" type="stateful"/>
> </kbase>
> </kmodule>
> {code}
> KAJR2 kmodule.xml:
> {code:xml}
> <kmodule xmlns="http://jboss.org/kie/6.0.0/kmodule">
> <kbase name="kbase2" equalsBehavior="equality" default="false" packages="rules2">
> <ksession name="ksession2" default="false" type="stateful"/>
> </kbase>
> </kmodule>
> {code}
> However, when both KieBases use the same "packages" name (e.g. 'rules'), only one of the resources gets included in the final KieBase.
> KJAR1 kmodule.xml:
> {code:xml}
> <?xml version="1.0" encoding="UTF-8"?>
> <kmodule xmlns="http://jboss.org/kie/6.0.0/kmodule">
> <kbase name="kbase1" equalsBehavior="equality" default="true" packages="rules" includes="kbase2">
> <ksession name="ksession1" default="true" type="stateful"/>
> </kbase>
> </kmodule>
> {code}
> KAJR2 kmodule.xml:
> {code:xml}
> <kmodule xmlns="http://jboss.org/kie/6.0.0/kmodule">
> <kbase name="kbase2" equalsBehavior="equality" default="false" packages="rules">

> API changes to be done in 4.0, which break code:
> * MessageDispatcher: remove MessageListener
> * Merge AsyncRequestHandler and RequestHandler, OR make them 2 separate interfaces, ie. AsyncRH doesn't extend RH
> * Remove @Deprecated methods, properties or classes
> * Remove direct access to Message in JChannel.send() methods (to prevent passing in the same message more than once)
> * Make {{RspFilter}} --> {{RspFilter<T>}}
> * {{ProtocolStack.findProtocol(Class<?> clazz)}} should return generic type {{<T extends Protocol>>}}, so no casting is needed. Requires changes to a number of methods in the same class.
> * Request<T>
> * RpcDispatcher: only 1 Marshaller, not separate ones for reqs and rsps
> * RpcDispatcher: use CompletableFuture instead of NotifiyingFuture
