Call crashed in JNI_CreateJavaVM with java 1.6 where as with 1.5 it works.

Question

Hi,
Recently we upgraded to Java 1.6 from 1.5. I have writed a code to launch JVM from C++ and use it. It was working with earlier version of Java 1.5 but the same
code is not working with Java 1.6.
We launch this process with differet users having adminstrative access. With default admin user it works no issues at all. But if we use Java 1.6 and change to the user who is having all administrative access it fails. Infact it hangs. Is i am missing anything. below is code snippet.
typedef JNIEnv* ( WINAPI*jvmFun ) ( JavaVM ** );
typedef JNIEnv* ( WINAPI*createJVMFun ) ();
typedef JNIIMPORT_OR_EXPORT_ jint ( JNICALL JNI_JVMPROC ) ( JavaVM *, void **, void * );
typedef JNIIMPORT_OR_EXPORT_ jint ( JNICALL JNI_GetCREATEDVMs ) ( JavaVM *, jsize, jsize * );
JNI_JVMPROC ProcAdd;
JNI_GetCREATEDVMs CreatedVms;
const int createJVM( JNIEnv* &env, string vm_options, HMODULE hinstLib)
     // Set JVM options
JavaVMOption *options = 0;
     options = new JavaVMOption[ options_size ];
//Fill options with runtime options here
     options[ (options_size - 1) ].optionString = java_options;
     // Set JVM initialization arguments
JavaVMInitArgs vm_args;
vm_args.version = JNI_VERSION_1_6;
vm_args.options = options;
vm_args.nOptions = options_size;
vm_args.ignoreUnrecognized = JNI_FALSE;
ProcAdd = ( JNI_JVMPROC ) GetProcAddress( hinstLib, "JNI_CreateJavaVM" );
jint createResult = ( ProcAdd ) ( &m_jvm, ( void** ) &env, &vm_args );
     jthrowable exc = env->ExceptionOccurred();
if (exc) {
env->ExceptionDescribe();
env->ExceptionClear();
     // exception
if ( createResult < 0 )
          free(java_options);
          delete [] options; // TODO: Need to clean each option string?
return FAILURE;
else
          free(java_options);
          delete [] options;// TODO: Need to clean each option string?
          return SUCCESS;
