Unable to run Logstash 8.3.1 (not even to check plugins): Errno::EACCES: Permission denied - NUL

Thanks to robbavey for pointing out that the Java option can be passed to JRuby using

set JRUBY_OPTS=-J-Djdk.io.File.enableADS=true

There is also now an open issue to get this fixed in the .bat files
