>Description:
Build the libgcj with option --enable-threads=none
Compile the following simple program:
----------------------
#include <iostream.h>

#include <jni.h>

int main(int argc, char* argv[])
{
  int nError = 0;
  JavaVMInitArgs sArgs;
  JavaVMOption sOptions[2];
  JavaVM *psMachine = (JavaVM *)0;
  void *pvEnv = (void *)0;

  sArgs.version = JNI_VERSION_1_2;
  JNI_GetDefaultJavaVMInitArgs(&sArgs);

  sOptions[0].optionString = "-Djava.compiler=NONE";
  sOptions[0].optionString = "-Djava.class.path=.:/usr/local/lib";

  nError = JNI_CreateJavaVM(&psMachine, &pvEnv, &sArgs);
  if (nError < 0)
  {
    cout << "Error: ";
    cout << nError;
    cout << " - JNI_CreateJavaVM()\n";
  } /* if */
  else
  {
  } /* else */

  return 0;
} /* main */
--------------------
Build the executable.
Run the executable, get an error when call JNI_CreateJavaVM().
Step through gdb, _Jv_JNI_AttachCurrentThread() returns NULL.
