Cannot use @DateBridge with WildFly modules: java.lang.NoClassDefFoundError: javax/xml/bind/DatatypeConverter ------------------------------------------------------------------------------------------------------------- Key: ISPN-6522 URL: https://issues.jboss.org/browse/ISPN-6522 Project: Infinispan Issue Type: Bug Components: Embedded Querying, WildFly modules Affects Versions: 8.2.1.Final, 9.0.0.Alpha1 Reporter: Gustavo Fernandes Assignee: Gustavo Fernandes Priority: Critical Fix For: 9.0.0.Alpha3, 8.2.3.Final The Hibernate Search engine detects if the elasticsearch backend is on the classpath, and if so, adds {{o.h.s.backend.elasticsearch.impl.ElasticsearchBridgeProvider}} to the top of the list of the annotation based bridge providers. When processing an entity with a @DateBridge annotation, it picks the elasticsearch provider to converted from/to {{Date}} objects (since it has priority) which in turn fails with the exception: {code} org.infinispan.commons.CacheException: java.lang.NoClassDefFoundError: javax/xml/bind/DatatypeConverter at org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:198) at org.jboss.modules.ConcurrentClassLoader.performLoadClassUnchecked(ConcurrentClassLoader.java:363) at org.jboss.modules.ConcurrentClassLoader.performLoadClass(ConcurrentClassLoader.java:351) at org.jboss.modules.ConcurrentClassLoader.loadClass(ConcurrentClassLoader.java:93) at org.hibernate.search.backend.elasticsearch.impl.ElasticsearchBridgeProvider$EsDateBridge.convertToString(ElasticsearchBridgeProvider.java:71) at org.hibernate.search.backend.elasticsearch.impl.ElasticsearchBridgeProvider$EsDateBridge.set(ElasticsearchBridgeProvider.java:54) at org.hibernate.search.bridge.util.impl.ContextualExceptionBridgeHelper$OneWayConversionContextImpl.set(ContextualExceptionBridgeHelper.java:110) at org.hibernate.search.engine.spi.DocumentBuilderIndexedEntity.buildDocumentFieldsForProperties(DocumentBuilderIndexedEntity.java:626) {code} This exception happens only when using the infinispan modules, where the elasticsearch backend is added as a dependency; in embedded mode the aforementioned provider is not loaded since the elasticsearch is not on the classpath. This current behaviour is not the best for two reasons: * When using Wildlfy modules, the elasticsearch backend is marked as optional, but still, it's visible in the classpath and gets loaded * If the user is not using the elasticsearch backend, but the jar is on the classpath, elasticsearch date conversion will take precedence over the built-in bridge providers, and it shouldn't
