Looking into the issue
The looger gem is broken after this commit was introduced. Testing the changes on the same Windows machine, I got to this code:
file_path = 'test.txt'
f = File.new(file_path, mode: File::CREAT)
f.flock(File::LOCK_EX)
f = File.new(f.fileno, mode: File::WRONLY, path: file_path)
f.flock(File::LOCK_UN)which fails with:
Unhandled Java exception: java.nio.channels.NonWritableChannelException
java.nio.channels.NonWritableChannelException: null
