[arquillian-issues] [JBoss JIRA] (ARQ-1027) Warp + Jacoco = NullPointerException

Warp + Jacoco = NullPointerException ------------------------------------ Key: ARQ-1027 URL: https://issues.jboss.org/browse/ARQ-1027 Project: Arquillian Issue Type: Bug Security Level: Public(Everyone can see) Components: Extension - Warp Affects Versions: warp_1.0.0.Alpha1 Reporter: Curtis McMillen Attachments: stacktrace.txt It seems there is a problem with running Warp tests if arquillian-jacoco is on the classpath. When WarpFilter fires the AfterSuite event, the writeCoverageData observer in arquillian-jacoco is executing which ultimately leads to a NPE coming from servlet protocol. The full stacktrace is attached. You can reproduce by simply adding the following dependencies to the pom for warp in arquillian-showcase and then running the BasicJSFUnitTestCase. {code:xml} <dependency> <groupId>org.jboss.arquillian.extension</groupId> <artifactId>arquillian-jacoco</artifactId> <version>1.0.0.Alpha3</version> <scope>test</scope> </dependency> <dependency> <groupId>org.jacoco</groupId> <artifactId>org.jacoco.core</artifactId> <version>0.5.7.201204190339</version> <scope>test</scope> </dependency> {code} Removing these dependencies isn't really an option because I have other arquillian tests not using Warp that I want code coverage on. I tried using alternative annotated with @Specializes thinking I could basically disable the observer in arquillian-jacoco simply by including a different beans.xml in the deployment of my Warp tests. This however fails with "WELD-000047 Specializing bean must extend another bean" which I'm thinking is due to https://issues.jboss.org/browse/WELD-1113. Any ideas for getting this to work?
