Hello!
File src/java.base/windows/native/libjava/WinNTFileSystem_md.c
The function getFinalPath() is wrapper for GetFinalPathNameByHandleW(),
which is used to resolve the symlinks on Windows.
If the resulting string begins with a prefix "\\?\" or "\\?\UNC", a copy
without the prefix is created and returned.
Instead of creating the copy, we can override the result with memmove()
to avoid allocating extra native memory.
The result of getFinalPath() is short living anyway, so a few unused
bytes at the end of the buffer should not be a problem.
The advantage is a shorter code and minus one point of possible failure.
Would you please help review it?
