The simple test for jni function NewDirectByteBuffer() is failed
on the jdk1.4.0-beta_refresh-b74 due to JVM crash.

To reproduce:
1. compile the ndbb00101m1.java
   Used: javac -d . ndbb00101m1.java
2. compile the gdbc00101m1.c
   Used: cc -G -KPIC -o libjckjni.so -Iinclude ndbb00101m1.c
   In 'include' directory you should place 3 files (see attachments):
   % ls include
   jckjlong_md.h jckjni.h jckjni_md.h

3. set environment variable LD_LIBRARY_PATH to working directory
4. run ndbb00101m1
   Used: java -Xfuture javasoft.sqe.tests.vm.jni.ndbb001.ndbb00101m1.ndbb00101m1

Execution log:
