[2] pry(main)> Open3.popen3("pwd", :chdir=>"/tmp") {|i,o,e,t|
[2] pry(main)*   puts "ok"  
[2] pry(main)* }  
ok
Java::JavaLang::ClassCastException: org.jruby.util.ShellLauncher$POpenProcess cannot be cast to org.jruby.util.io.POSIXProcess
from org.jruby.RubyIO.rbIoClose(RubyIO.java:1802)

I'm using:
jruby 9000.dev-SNAPSHOT (2.1.2) 2014-08-06 22bf660 OpenJDK 64-Bit Server VM 24.65-b04 on 1.7.0_65-mockbuild_2014_07_17_14_16-b00 [linux-amd64]

btw in non-block syntax it seems to be working without errors:

[4] pry(main)> Open3.popen3("pwd", :chdir=>"/")
=> [#<IO:0x5d80186a>,
 #<IO:0x7f26ca93>,
 #<IO:0x4bbdba1c>,
 #<Process::WaitThread:0x1505ab1d dead>]

UPDATE: another issue I see is capture2. It must be returning status according to ruby docs but it apears to be returning a process id:

[16] pry(main)> o,s = Open3.capture2('echo asd', :chdir=>"/tmp")
=> ["asd\n", 5262]

This is MRI output:

[3] pry(main)> o,s = Open3.capture2('pwd', :chdir=>"/tmp")
=> ["/tmp\n", #<Process::Status: pid 5401 exit 0>]

long-time-since but this seem to be doing well on JRuby 9.1.9.0 :

jruby-9.1.9.0 :001 > require 'open3'
 => true 
jruby-9.1.9.0 :002 > o,s = Open3.capture2('echo asd', :chdir=>"/tmp")
 => ["asd\n", #<Process::Status: pid 2932 exit 0>] 
jruby-9.1.9.0 :003 > Open3.popen3("pwd", :chdir=>"/tmp") { |i,o,e,t| puts "ok"; }
ok
 => nil
