Dan Berindei created ISPN-10879: ----------------------------------- Summary: PersistenceIT random failures Key: ISPN-10879 URL: https://issues.jboss.org/browse/ISPN-10879 Project: Infinispan Issue Type: Bug Reporter: Dan Berindei {noformat} java.lang.NoClassDefFoundError: Could not initialize class org.infinispan.server.persistence.PersistenceIT {noformat} The reason for the error is that {{PersistenceIT}} has a static final field {{InfinispanServerRule SERVERS}}, and the {{InfinispanServerRule}} constructor may throw an exception. The first time the JVM tries to initialize the {{PersistenceIT}} class, the caller gets an {{ExceptionInInitializerError}}, but further attempts get the {{NoClassDefFoundError}} instead. And since this is all inside Surefire/JUnit, the initial {{ExceptionInInitializerError}} is ignored somewhere without being logged. To help debugging via logs, the constructor should be trivial, and the {{serverDriver}} should only be initialized in the {{apply()}} method. -- This message was sent by Atlassian Jira (v7.13.8#713008)
