      Description

      Please refer to Incident #144059 filed by Sitraka :

      Registering interest in JVMPI_EVENT_METHOD_EXIT will occasionaly cause client JVMs to hang after an indeterminate amount of time. The JVMs affected by this include

      1.3.1_01
      1.3.1_01a
      1.3.1_02
      1.4.0-b92

      Platform -- at least win32 (reproduced on Win2K, NT4).

      The 1.3.1-b24 JVM is not affected by this problem.

      HPROF can be used to demonstrate this behaviour by adding "-Xrunhprof:cpu=times" to the command line arguments of the JVM.

      A moderately large application is required in order to reproduce the problem. Tomcat 4.0.1 or WebLogic6.1sp2 are good candidates -- the hang occurs on startup (between 1 and 2 minutes into running the application). For the 1.3.1_0x JVMs, the hang does not cause the application to exit -- the JVM becomes unresponsive and does not report any errors. The 1.4 JVM exits with the error printed below. The hang does not occur every run.

      ----------- end sample Tomcat 4 run -------------

      HPROF reports stack problems regardless of whether the hang (or crash for the 1.4 JVM) occurs.

      The following code can be used as 'the simplest' JVMPI client able to reproduce the problem:

      ----------- sample code -------------

      #include <jvmpi.h>

      JVMPI_Interface * jvmpi;
      static void notify(JVMPI_Event *);

      JNIEXPORT jint JNICALL
      JVM_OnLoad(JavaVM * jvm, char * options, void * reserved) {

      (*jvm)->GetEnv(jvm, (void **) &jvmpi, JVMPI_VERSION_1);
      jvmpi->NotifyEvent = notify;
      jvmpi->EnableEvent(JVMPI_EVENT_METHOD_EXIT, 0);
      return JNI_OK;
      }

      static void
      notify(JVMPI_Event * event) {
      return;
      }

      -------------------------

      I ran the same test on Windows 2000 machine using Tomcat 4.0 (Modified catalina.bat script to include -Xrunhprof:cpu=times) and Java 1.4 FCS (buld 92). I can see HPROF errors, but the crash is not consistent. Tomcat is running fine some times, but fails some other times. There are many bug reports filed for similar issue, but could not find any thing which matches exactly the same description.
