Michael Mellenthin created ISPN-2730: ---------------------------------------- Summary: Not possible to instanciate org.infinispan.cdi.InfinispanExtension during startup of appserver Key: ISPN-2730 URL: https://issues.jboss.org/browse/ISPN-2730 Project: Infinispan Issue Type: Bug Components: CDI integration Affects Versions: 5.2.0.CR1 Environment: tested in openEJB Reporter: Michael Mellenthin Assignee: Pete Muir Priority: Critical I have infinispan-cdi library in my appserver to be able to use JSR-107. During startup of application server it loads the InfinispanExtension because the service provider is declared in META-INF/services. During startup I get the exception {code} Caused by: java.util.ServiceConfigurationError: javax.enterprise.inject.spi.Extension: Provider org.infinispan.cdi.InfinispanExtension could not be instantiated: java.lang.IllegalAccessException: Class java.util.ServiceLoader$LazyIterator can not access a member of class org.infinispan.cdi.InfinispanExtension with modifiers "" at java.util.ServiceLoader.fail(ServiceLoader.java:207) at java.util.ServiceLoader.access$100(ServiceLoader.java:164) at java.util.ServiceLoader$LazyIterator.next(ServiceLoader.java:353) at java.util.ServiceLoader$1.next(ServiceLoader.java:421) {code} The reason is that the InfinispanExtension only provides a package scoped constructor. For sure the documentation of java.util.ServiceLoader is not very clear here. It just says: "The only requirement enforced by this facility is that provider classes must have a zero-argument constructor so that they can be instantiated during loading" But the implementation fails if the constructor is not public. Hence, we need a public constructor for InfinispanExtension. -- This message is automatically generated by JIRA.
