See bug report for reproducer and error message. The warning looks quite superficial, and I initially suspected that it complains about `int len = (int)strlen(str)` cast of `size_t`. But what is confusing is nearly the similar code in `newStringCp1252` apparently does not produce the warning: https://github.com/openjdk/jdk/blob/f5d1b5bda27c798347ae278cbf69725ed4be895c/src/java.base/share/native/libjava/jni_util.c#L533-L566
I propose we chalk it up to false/odd compiler warning and sync up unproblematic `newStringCp1252` and `newString646_US` implementation to dodge it.
