     ::testing::Test::RecordProperty(name, buf);
-    snprintf(buf, JVM_MAXPATHLEN, "%d", (int) wcslen(path));
+    os::snprintf(buf, JVM_MAXPATHLEN, "%d", (int) wcslen(path));
     ::testing::Test::RecordProperty(len_name, buf);
   }

This follows the relevant Windows build fixes: we use os::snprintf [1].

Testing: windows build, gtest:os (runs affected test)
