The JVM crashes when leaving native code when a nested exception has been
thrown. The following code crashes consistantly on Solaris 2.7 under Java 1.3
(with both "-client" and "-server") and Java1.2.2_05a:

*** JAVA CLASSES ***

public class Test {

    static {
System.loadLibrary("test");
    }

    public static void main(String args[]) throws Exception {
throwException();
    }

    private static final native void throwException() throws Exception;
}

class NestedException extends Exception {
  Throwable cause = null;

  NestedException(String msg) {
    super(msg);
  }

  NestedException(String msg, Throwable cause) {
    super(msg);
    this.cause = cause;
  }
}

*** Native function ***

#include "Test.h"

JNIEXPORT void JNICALL Java_Test_throwException(JNIEnv *env, jclass jthis) {
  jclass clazz = env->FindClass("NestedException");
  if (clazz == NULL) {
    return;
  }

  jmethodID mid = env->GetMethodID(clazz, "<init>","(Ljava/lang/String;Ljava/lang/Throwable;)V");
  if (mid == NULL) {
    return;
  }

  printf("Throwing initial exception\n");
  env->ThrowNew(clazz, "initial exception");

  jthrowable cause = env->ExceptionOccurred();
  env->ExceptionClear();
  jthrowable e = (jthrowable) env->NewObject(clazz, mid, "second exception", cause);
  printf("Throwing second exception: e=0x%08x\n", e);
  env->Throw(e);

  printf("Leaving native code\n");
}

*** Output ***
