EmptyStackException in Transaction.java --------------------------------------- Key: JBSEAM-1696 URL: http://jira.jboss.com/jira/browse/JBSEAM-1696 Project: JBoss Seam Issue Type: Bug Affects Versions: 2.0.0.BETA1 Environment: Seam cvs 20070717.1711 Reporter: Matt Drees Priority: Minor I occasionally get the following stacktrace. I believe it happens when the SeamPhaseListener tries to begin a transaction, but an exception is thrown, so the stack is never pushed. Later, when it tries to commitOrRollback, the following happens. 2007-07-18 15:29:55,229 ERROR () SeamPhaseListener: uncaught exception java.lang.IllegalStateException: Could not commit transaction at org.jboss.seam.jsf.SeamPhaseListener.commitOrRollback(SeamPhaseListener.java:589) at org.jboss.seam.jsf.SeamPhaseListener.handleTransactionsAfterPhase(SeamPhaseListener.java:325) at org.jboss.seam.jsf.SeamPhaseListener.afterServletPhase(SeamPhaseListener.java:226) at org.jboss.seam.jsf.SeamPhaseListener.afterPhase(SeamPhaseListener.java:184) at com.sun.faces.lifecycle.LifecycleImpl.phase(LifecycleImpl.java:280) at com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:117) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:244) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:82) at org.jboss.seam.debug.hot.HotDeployFilter.doFilter(HotDeployFilter.java:68) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:68) at org.jboss.seam.web.MultipartFilter.doFilter(MultipartFilter.java:85) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:68) at org.jboss.seam.web.ExceptionFilter.doFilter(ExceptionFilter.java:61) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:68) at org.jboss.seam.web.RedirectFilter.doFilter(RedirectFilter.java:44) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:68) at org.ajax4jsf.framework.ajax.xmlfilter.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:127) at org.ajax4jsf.framework.ajax.xmlfilter.BaseFilter.doFilter(BaseFilter.java:277) at org.jboss.seam.web.Ajax4jsfFilter.doFilter(Ajax4jsfFilter.java:60) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:68) at org.jboss.seam.web.LoggingFilter.doFilter(LoggingFilter.java:58) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:68) at org.jboss.seam.servlet.SeamFilter.doFilter(SeamFilter.java:149) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:869) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:80) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684) at java.lang.Thread.run(Thread.java:595) Caused by: java.util.EmptyStackException at java.util.Stack.peek(Stack.java:79) at org.jboss.seam.transaction.Transaction.beforeCommit(Transaction.java:64) at org.jboss.seam.transaction.UTTransaction.commit(UTTransaction.java:44) at org.jboss.seam.jsf.SeamPhaseListener.commitOrRollback(SeamPhaseListener.java:579) You'd probably just need a simple "if (!synchronizations.isEmpty())" check before peek()ing or pop()ing. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
