我在运行脚本时遇到此错误。我对Ruby很陌生，所以请原谅我的傲慢。
我正在使用内置JRuby支持的Nuix编写脚本。
这是我的代码;
require 'benchmark'
require 'socket'
require 'rubygems'
require 'java'
java_import org.joda.time.format.DateTimeFormat

include_package javax.swing
end
def dropdown()
ar = Array.new
$current_case.getRootItems().each do set
ar set.guid()
end
names2 = JSwingJOptionPane.showInputDialog(nil, Please enter the name of the item set to export to Relativity.,
Choose item set, -1,
nil, ar.to_java(Object), ar[0])
if (names2.nil)
JSwingJOptionPane.showMessageDialog(nil, No Export Set Selected)
abort()
end
return names2
end

File.open(filepath, 'a') { f1 f1.puts line }
end

f2.print uFEFF
lines.each do line
count += 1
if count % 1000 == 0
#progress.update_progress(count)
end
f2.puts line
end
#frame.dispose

这是不断被抛出的例外;

我相信可能会被checknull函数抛出，但我无法确定。
感谢任何帮助。
