Errno::EACCES: Permission denied - NUL not fixed with enableADS

Elastic Stack Logstash

Running logstash (latest version 8.3.2) on Windows gives me:

Errno::EACCES: Permission denied - NUL
sysopen at org/jruby/RubyIO.java:1237

Found out that this is a known issue and fixed with -Djdk.io.File.enableADS=true, but that does not work for me.
Any assistance would be helpful.

Looks like logstash-plugin does not even use the jvm.options file. When I rename that file this is the result

C:\test\logstash-8.3.2>bin\logstash.bat
"Using bundled JDK: C:\test\logstash-8.3.2\jdk\bin\java.exe"
Warning: no jvm.options file found.
Terminate batch job (Y/N)? y

C:\test\logstash-8.3.2>bin\logstash-plugin.bat
"Using bundled JDK: C:\test\logstash-8.3.2\jdk\bin\java.exe"
Usage:
    bin/logstash-plugin [OPTIONS] SUBCOMMAND [ARG] ...

It does not complain about the missing jvm.options file.
Any idea how I could set this enableADS property?

See this thread. Follow the link to the github issue for additional colour.

Note that this was fixed in 8.3.3, which just released.
