Subject [jira] Created: (HARMONY-1850) [drlvm] VM reports Internal Error when -Djava.library.path oprion is specified

[drlvm] VM reports Internal Error when -Djava.library.path oprion is specified
------------------------------------------------------------------------------

                 Key: HARMONY-1850
                 URL: http://issues.apache.org/jira/browse/HARMONY-1850
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
         Environment: Windows and Linux
            Reporter: Vera Petrashkova


VM reports Internal Error and can not start when -Djava.library.path option is specified.

When environment variables PATH and LD_LIBRARY_PATH are not specified then
VM correctly throws 
         UnsatisfiedLinkageError: Can not find library...

But if -Djava.library.path option is defined in addition to PATH/LD_LIBRARY_PATH or without
these variables specification
then VM does not start and reports the following error message:
   HMYEXEL062E Internal VM error: Failed to create Java VM
   FAILED to invoke JVM.

Code for reproducing:
---------------JNITest.java----------------
public class JNITest {

    public static native void Hello();

    public static void main (String argv[]) {
        new JNITest().test();
    }

    public void test() {
        Hello();  
    }

    static {
        System.loadLibrary("JNITest");
    }
}
------------------JNITest.c-----------------------
#include <jni.h>
#include <stdio.h>

JNIEXPORT void JNICALL Java_JNITest_Hello (JNIEnv *env, jclass cls) {
  printf("Hello!\n");
}
------------------------------------------------------

1) Create test libraries or use them from attachment
2) Set library to some "tmp" directory
3) Run test

   java -cp . -Djava.library.path=tmp JNITest
