Please, review small patch to fix the build regression caused by fix of 8242237.

Patch:

 /* Process a CLASS_LOAD or aClassPrepare event. */
 static void process_class_event(jvmtiEnv* jvmti, JNIEnv* jni, jclass klass,

   char* sig = NULL;
   char* gsig = NULL;
   jvmtiError err;


Summary:
  Windows Compiler reports errors when a parameter is declared as 'int*' but jint* is actually used in the calls:

./open/test/hotspot/jtreg/serviceability/jvmti/HiddenClass/libHiddenClassSigTest.cpp(271): error C2664: 'void process_class_event(jvmtiEnv *,JNIEnv *,jclass,int *,const char *)': cannot convert argument 4 from 'jint *' to 'int *'
./open/test/hotspot/jtreg/serviceability/jvmti/HiddenClass/libHiddenClassSigTest.cpp(271): note: Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast


Testing:
  A mach5 job build-tier1 submitted.

Thanks,
