    Posted by Seth Jackson on the user forum[1]. It appears something was modified in OpenJPA 2.0 M3 from M2 that causes a LinkageError. In my current environment, I've tested both Glassfish and Tomcat using M2 and M3. M2 runs without problems, but M3 throws a linkage error as follows: Caused by: java.lang.LinkageError: loader constraint violation: loader (instance of sun/misc/Launcher$AppClassLoader) previously initiated loading for a different type with name "org/apache/openjpa/conf/OpenJPAConfiguration" at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:621) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124) at java.net.URLClassLoader.defineClass(URLClassLoader.java:260) at java.net.URLClassLoader.access$000(URLClassLoader.java:56) at java.net.URLClassLoader$1.run(URLClassLoader.java:195) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) at org.apache.openjpa.persistence.validation.ValidationUtils.setupValidation(ValidationUtils.java:53) at org.apache.openjpa.persistence.PersistenceProviderImpl.loadValidator(PersistenceProviderImpl.java:290) at org.apache.openjpa.persistence.PersistenceProviderImpl.createEntityManagerFactory(PersistenceProviderImpl.java:97) at org.apache.openjpa.persistence.OpenJPAPersistence.createEntityManagerFactory(OpenJPAPersistence.java:128) at org.apache.openjpa.persistence.OpenJPAPersistence.createEntityManagerFactory(OpenJPAPersistence.java:111) at test_test.user.UserAction.execute(UserAction.java:39) I've already confirmed that the OpenJPA classes in question do NOT exist in any other JARs in the path. ValidationUtils.setupValidation(ValidationUtils.java:53) calls the OpenJPAConfiguration.getConfigurationLog(). The object being referenced is JDBCConfigurationImpl, which in other classes retrieves the log reference perfectly fine, before it gets to the offending line. Seth's follow up[2]: After further review, using Glassfish 2.1.1 I received this error message in the server log: Caused by: java.lang.LinkageError: loader constraint violation: when resolving method "org.apache.openjpa.persistence.validation.ValidationUtils.setupValidation(Lorg/apache/openjpa/conf/OpenJPAConfiguration;)Z" the class loader (instance of org/apache/catalina/loader/WebappClassLoader) of the current class, org/apache/openjpa/persistence/PersistenceProviderImpl, and the class loader (instance of sun/misc/Launcher$AppClassLoader) for resolved class, org/apache/openjpa/persistence/validation/ValidationUtils, have different Class objects for the type org/apache/openjpa/conf/OpenJPAConfiguration used in the signature So it appears to be the WebappClassLoader and the AppClassLoader are both loading the OpenJPAConfiguration from the same JAR file, causing the error when the class is trying to be resolved in this particular method.
