When using the filesystem provider on a localized RUSSIAN Windows system putBlob consistenly throws a RuntimeException. The put operation does succeed, however, meaning a viable workaround is to catch-and-ignore.
The cause of the Exception is a UserPrincipalNotFoundException which is thrown in org.jclouds.filesystem.util.Utils while trying to resolve the Windows SID 'S-1-1-0' user group using UserPrincipalLookupService.lookupPrincipalByName.
The Russian translation for everyone is "Все", and the output of the "whoami" command will be in https://de.wikipedia.org/wiki/Codepage_866 wich turns into different characters, when read into a java string via "ProcessBuilder.start". This is the reason why the "lookupPrincipalByName" fails.
This will occur on all windows systems, where the translation contains non standard ASCII 7 bit characters. See also https://www.microsoft.com/en-us/language/Search?&searchTerm=Everyone&langID=Russian&Source=true&productid=All%20Products
