[9] RFR JDK-8141616: Add new methods to the java Whitebox API

[Christian Thalinger]

+WB_ENTRY(jint, WB_GetConstantPoolCacheLength(JNIEnv* env, jobject wb, jclass klass))
+  instanceKlassHandle ikh(java_lang_Class::as_Klass(JNIHandles::resolve(klass)));
+  ConstantPool* cp = ikh->constants();
+  if (cp->cache() == NULL) {
+      return -1;
+  }

Shouldn’t this throw an exception like in the other methods?
