Improve exception message when package-info / other file is missing @ metadatasources.buildMetadata() ----------------------------------------------------------------------------------------------------- Key: HHH-6632 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6632 Project: Hibernate Core Issue Type: Improvement Components: metamodel Affects Versions: 4.0.0.CR2 Reporter: Elmer van Chastelet While migrating our project to the new Hibernate Core 4.0, I came across an exception which was thrown during metadatasources.buildMetadata(). Emmanuel helped me to find the cause, which were the missing package-info.java files for the packages I add to the MetadataSources object. If possible, improve this exception message to include info about the file that fails to load. {code} Sep 5, 2011 4:17:46 PM org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Allocate exception for servlet mainservlet java.io.IOException: Stream closed at java.io.BufferedInputStream.getInIfOpen(BufferedInputStream.java:151) at java.io.BufferedInputStream.fill(BufferedInputStream.java:235) at java.io.BufferedInputStream.read1(BufferedInputStream.java:275) at java.io.BufferedInputStream.read(BufferedInputStream.java:334) at java.io.DataInputStream.readFully(DataInputStream.java:195) at java.io.DataInputStream.readFully(DataInputStream.java:169) at org.jboss.jandex.Indexer.verifyMagic(Indexer.java:387) at org.jboss.jandex.Indexer.index(Indexer.java:628) at org.hibernate.metamodel.source.annotations.AnnotationMetadataSourceProcessorImpl.indexClass(AnnotationMetadataSourceProcessorImpl.java:159) at org.hibernate.metamodel.source.annotations.AnnotationMetadataSourceProcessorImpl.prepare(AnnotationMetadataSourceProcessorImpl.java:85) at org.hibernate.metamodel.source.internal.MetadataImpl.prepare(MetadataImpl.java:180) at org.hibernate.metamodel.source.internal.MetadataImpl.<init>(MetadataImpl.java:165) at org.hibernate.metamodel.source.internal.MetadataBuilderImpl.buildMetadata(MetadataBuilderImpl.java:83) at org.hibernate.metamodel.MetadataSources.buildMetadata(MetadataSources.java:112) at utils.HibernateUtilConfigured.<clinit>(HibernateUtilConfigured.java:60) at utils.DispatchServlet.tryLoadGlobalsAndPerformInit(DispatchServlet.java:19) at utils.DispatchServlet.init(DispatchServlet.java:39) at javax.servlet.GenericServlet.init(GenericServlet.java:212) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1173) at org.apache.catalina.core.StandardWrapper.allocate(StandardWrapper.java:809) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:129) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:555) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:857) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) at java.lang.Thread.run(Thread.java:679) {code} -- This message is automatically generated by JIRA.
