A DESCRIPTION OF THE PROBLEM :
Please Look "Steps to Reproduce" section and "Source code for an executable test case:"

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Bug occurs in JNI code:
URL Object returns NULL in JNI code:

 jclass URLClazz = (*env)->FindClass(env, "java/net/URL");

jmethodID mid = (*env)->GetMethodID(env, URLClazz, "<init>", "(Ljava/lang/String;)V");

string URLString = (*env)->NewStringUTF(env, str2);

jobject URLObject = (*env)->NewObject(env, URLClazz, mid, URLString);

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
URLObject shouldn't return NULL
ACTUAL -
URLObject returns NULL, It shouldn't return NULL.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
jclass URLClazz = (*env)->FindClass(env, "java/net/URL");

mid = (*env)->GetMethodID(env, URLClazz, "<init>", "(Ljava/lang/String;)V");


//const char *str3 = &str2[0];

jstring URLString = (*env)->NewStringUTF(env, str2);

jobject URLObject = (*env)->NewObject(env, URLClazz, mid, URLString);

mid = (*env)->GetMethodID(env, URLClazz, "openConnection", "()Ljava/net/URLConnection;");


//below two line values is null URLObject and URLConnection than it throws exception
jobject URLConnection = (*env)->CallObjectMethod(env, URLObject, mid);
jclass URLConnectionClazz = (*env)->GetObjectClass(env, URLConnection);
