[jboss-jira] [JBoss JIRA] (WFCORE-4674) Custom handlers, formatters and filters cause the server to crash if the log manager is on the boot class path

Custom handlers, formatters and filters cause the server to crash if the log manager is on the boot class path -------------------------------------------------------------------------------------------------------------- Key: WFCORE-4674 URL: https://issues.redhat.com/browse/WFCORE-4674 Project: WildFly Core Issue Type: Bug Components: Logging Reporter: James Perkins Assignee: James Perkins Priority: Critical Labels: OpenShift, jdk11 Fix For: 13.0.0.Beta1 If the log manager is on the boot class path with Java 11, {{-Xbootclasspath/a:jboss-logmanager.jar}}, and a custom handler, formatter or filter is used the server will fail to boot as the log manager can't see the types in jboss-modules. This seems due to the fact that the log manager is on the boot class path and jboss-modules is on the system class path. Example exception: {code} Failed to read or configure the org.jboss.logmanager.LogManager java.lang.IllegalArgumentException: Failed to load module "org.jboss.logmanager" for formatter "JSON" at org.jboss.logmanager.config.AbstractPropertyConfiguration.<init>(AbstractPropertyConfiguration.java:65) at org.jboss.logmanager.config.FormatterConfigurationImpl.<init>(FormatterConfigurationImpl.java:30) at org.jboss.logmanager.config.LogContextConfigurationImpl.addFormatterConfiguration(LogContextConfigurationImpl.java:172) at org.jboss.logmanager.PropertyConfigurator.configureFormatter(PropertyConfigurator.java:631) at org.jboss.logmanager.PropertyConfigurator.configureHandler(PropertyConfigurator.java:701) at org.jboss.logmanager.PropertyConfigurator.configureLogger(PropertyConfigurator.java:583) at org.jboss.logmanager.PropertyConfigurator.configure(PropertyConfigurator.java:521) at org.jboss.logmanager.PropertyConfigurator.configure(PropertyConfigurator.java:97) at org.jboss.logmanager.LogManager.readConfiguration(LogManager.java:170) at org.jboss.logmanager.LogManager.readConfiguration(LogManager.java:132) at java.util.logging.LogManager$3.run(LogManager.java:399) at java.util.logging.LogManager$3.run(LogManager.java:396) at java.security.AccessController.doPrivileged(Native Method) at java.util.logging.LogManager.readPrimordialConfiguration(LogManager.java:396) at java.util.logging.LogManager.access$800(LogManager.java:145) at java.util.logging.LogManager$2.run(LogManager.java:345) at java.security.AccessController.doPrivileged(Native Method) at java.util.logging.LogManager.ensureLogManagerInitialized(LogManager.java:338) at java.util.logging.LogManager.getLogManager(LogManager.java:378) at org.jboss.modules.Main.main(Main.java:523) Caused by: java.lang.NoClassDefFoundError: org/jboss/modules/ModuleLoader at org.jboss.logmanager.config.AbstractPropertyConfiguration$ModuleFinder.getClassLoader(AbstractPropertyConfiguration.java:556) at org.jboss.logmanager.config.AbstractPropertyConfiguration.<init>(AbstractPropertyConfiguration.java:63) ... 19 more {code}
