The JNI_GetStringCritical method does not lock the char array in the !is_latin case, but returning it to the caller.

I think the string object can actually be unlocked at end of the method in this case as it is never returned to the C code (just the char array, but this one is not locked at all).

May cause crashes with gcs supporting object pinning (that is Shenandoah).

Found after looking at the suggestion in ~~JDK-8269650~~.
