Java HotSpot Virtual Machine

Hi
I am callin java method from C function using JNI.
I want to return string or array of strings from java method.
However program is crashing at run time.

Code for returning array of strings is as below:
Java code:

public class Cello
{	
  public static String[] abc(String[] args)
    	{
		String[] strRetOP = new String[2];
		
		System.out.println("Hello JAVA .... !");
		
		strRetOP[0]="SUCCESS";
		return strRetOP;		
	}
	public static void main (String[] args)
	{	
	}
}

C code snippet:

jobjectArray args2 , args5OP ;
jstring jstr2[NUM],   jstr3,  jstr5OP;
:
id2_main = (*env)->GetStaticMethodID(env, stringClass2,"abc", "(Ljava/lang/String;)Ljava/lang/String");
:
jstr3 = (*env)->FindClass(env, "java/lang/String");
:
args2 = (*env)->NewObjectArray(env, NUM, jstr3, jstr2[0] );
:
jstr5OP = (*env)->FindClass(env, "java/lang/String");
args5OP =  (*env)->NewObjectArray(env, NUM2, jstr5OP, jstr2[0] );
	for(i=1;i<NUM2;i++)
		(*env)->SetObjectArrayElement(env, args5OP, i, jstr2);



jstr5OP = (*env)->CallStaticObjectMethod(env, stringClass2, id2_main, args2);

:
I could execute program successfully with java returning integer and C function calling id2_main = (*env)->GetStaticMethodID(env, stringClass2,"abc", "([Ljava/lang/String;)I"); and CallStaticIntMethod. 

However program is crashing when java method is changed to return array  of Strings instead of int.
Can anybody please help?
