[hibernate-issues] [Hibernate-JIRA] Updated: (HSEARCH-1115) Failure to load Analyzer class when deployed into AS7

Failure to load Analyzer class when deployed into AS7 ----------------------------------------------------- Key: HSEARCH-1115 URL: https://hibernate.onjira.com/browse/HSEARCH-1115 Project: Hibernate Search Issue Type: Bug Components: engine Affects Versions: 4.1.0.Final Reporter: Randall Hauch Fix For: 4.1.1.Final, 4.2 Specifying an analyzer class via the "hibernate.search.analyzer" configuration property results in an exception when initializing the Hibernate Search engine within the AS7 environment: {code} Caused by: org.hibernate.search.SearchException: Analyzer found with an unknown definition: org.apache.lucene.analysis.standard.StandardAnalyzer at org.hibernate.search.impl.ConfigContext.initLazyAnalyzers(ConfigContext.java:252) at org.hibernate.search.spi.SearchFactoryBuilder.initDocumentBuilders(SearchFactoryBuilder.java:434) at org.hibernate.search.spi.SearchFactoryBuilder.buildNewSearchFactory(SearchFactoryBuilder.java:221) at org.hibernate.search.spi.SearchFactoryBuilder.buildSearchFactory(SearchFactoryBuilder.java:145) ... {code} Even setting the "hibernate.search.analyzer" property to "org.apache.lucene.analysis.standard.StandardAnalyzer" (which happens to be the default if no analyzer class is specified) will also fail. I believe this exception is occurring within the AS7 module class loading environment because during initialization of the Hibernate Search engine (e.g., {{SearchFactoryBuilder.buildSearchFactory}}), the {{ConfigContext.initAnalyzer}} method is called and uses Hibernate's {{ReflectionHelper}} class to try to load the analyzer class (see [this code|https://github.com/hibernate/hibernate-search/blob/4.1.0.Final/hiber...]). The {{ReflectionHelper}} uses the Thread context class loader to try to find the class or (if that fails) the class's class loader; neither of these work in AS7's module system, unless the JARs with the analyzer are defined within the "org.hibernate" module. A better solution needs to be found in order for the analyzer class to be specified. Ideally, the solution should be flexible enough so that any AS7 subsystem that uses Hibernate Search can specify the analyzer classname and module.
