I don't know enough about the security stuff to troubleshoot any further.

Does the "test-security-manager" ant target work for you? A way to troubleshoot further would be to use the sample security policy in test/restricted.policy like so:

jruby -d -J-Djava.security.manager= -J-Djava.security.policy=file:test/restricted.policy -S irb

And see what blows up.

Oh, you can ignore about the last error message about 'wirble'; it's from my ~/.irbrc.

...and also the Win32API error message as well. If I remove ~/.irbrc, 'bin/jruby -d -J-D...' brings up the IRB prompt with any error message.
