Problems with CDI Builder and scanning Jars which support Java 9 ---------------------------------------------------------------- Key: JBIDE-25441 URL: https://issues.jboss.org/browse/JBIDE-25441 Project: Tools (JBoss Tools) Issue Type: Bug Components: cdi, common Affects Versions: 4.5.1.Final, 4.5.2.AM1 Reporter: Nick Boldt Assignee: Jeff MAURY Fix For: 4.5.2.AM3 As reported in https://developer.jboss.org/message/978446?et=watches.email.thread#978446: {quote} Setup: * Eclipse Oxygen 4.7.1 * JBoss Tools 4.5.1.Final (also tested with latest development version 4.5.2.AM1) * An maven web application with certain dependencies ** So far, we found two dependencies, which lead to this jandex scaning error after upgrading to latest version ** org.apache.logging.log4j version 2.10.0 ** org.ow2.asm version 6.0 This leads to an CDI Builder IllegalStateException - see exception trace below. Both dependencies started support for Java 9, which seems to cause this exception. *Apache Log4j 2.10.0 released*: http://mail-archives.apache.org/mod_mbox/www-announce/201711.mbox/%3Cdf95... {code} !MESSAGE Errors running builder 'CDI (Contexts and Dependency Injection) Builder' on project 'Webapp'. !STACK 0 java.lang.IllegalStateException: Unknown tag! pos=4 poolCount = 24 at org.jboss.jandex.Indexer.processConstantPool(Indexer.java:665) at org.jboss.jandex.Indexer.index(Indexer.java:699) at org.jboss.tools.common.core.jandex.JandexUtil.createJarIndex(JandexUtil.java:56) at org.jboss.tools.common.core.jandex.JandexUtil.hasAnnotation(JandexUtil.java:104) at org.jboss.tools.cdi.internal.core.scanner.lib.BeanArchiveDetector.hasAnnotatedBeans(BeanArchiveDetector.java:276) at org.jboss.tools.cdi.internal.core.scanner.lib.BeanArchiveDetector.resolve(BeanArchiveDetector.java:203) at org.jboss.tools.cdi.internal.core.scanner.lib.ClassPathMonitor.detectBeanModule(ClassPathMonitor.java:150) at org.jboss.tools.cdi.internal.core.scanner.lib.ClassPathMonitor.process(ClassPathMonitor.java:106) at org.jboss.tools.cdi.core.CDICoreBuilder.build(CDICoreBuilder.java:215) at org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:735) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:206) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:246) at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:301) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:304) at org.eclipse.core.internal.events.BuildManager.basicBuildLoop(BuildManager.java:360) at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:383) at org.eclipse.core.internal.events.AutoBuildJob.doBuild(AutoBuildJob.java:142) at org.eclipse.core.internal.events.AutoBuildJob.run(AutoBuildJob.java:232) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:56) {code} {quote}
