Edoardo Vacchi created DROOLS-3328: -------------------------------------- Summary: PhreakAsyncSendNode triggers service discovery even when it's not used Key: DROOLS-3328 URL: https://issues.jboss.org/browse/DROOLS-3328 Project: Drools Issue Type: Enhancement Reporter: Edoardo Vacchi Assignee: Edoardo Vacchi I am investigating ways to startup a stripped down version of the rule engine. in 7.8.0 the following snippet did _not_ trigger service discovery : {code} CanonicalKiePackages packages = new MyKiePackagesBuilder(model, ProjectClassLoader.createProjectClassLoader()).build(); InternalKnowledgeBase kBase = new KnowledgeBaseImpl("defaultname", null); kBase.addPackages(packages.getKiePackages()); kieSession = kBase.newKieSession(); {code} this is because no call to {{ExecutorProviderFactory.getExecutorProvider()}} occurs anywhere. However in a recent release, {{PhreakAsyncSendNode}} invokes this method, while initializing a static field {code} private static final Executor executor = ExecutorProviderFactory.getExecutorProvider().getExecutor(); {code} This triggers a *full service discovery* which loads a bunch of other unrelated services. Solution: avoid service discovery in that class, or delegate to a method (the service utility caches that field anyway, so it's not necessary to set a static field there) -- This message was sent by Atlassian Jira (v7.12.1#712002)
