Please review this small fix for a return code handling of windows function CloseHandle .
MSDN documents CloseHandle here : https://msdn.microsoft.com/de-de/library/windows/desktop/ms724211(v=vs.85).aspx .... Return value If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. To get extended error information, call GetLastError<https://msdn.microsoft.com/de-de/library/windows/desktop/ms679360(v=vs.85).aspx>. However until this patch, Java_java_io_FileCleanable_cleanupClose0 Checked for return code -1 of CloseHandle in error cases . Bug: https://bugs.openjdk.java.net/browse/JDK-8205416 Webrev : http://cr.openjdk.java.net/~mbaesken/webrevs/8205416/ Thanks, Matthias
