Description

I attached simple test tools isatty to demonstrate this bug.

$ ruby -v
ruby 1.8.7 (2010-06-23 patchlevel 299) [x86_64-linux]

$ jruby -v
jruby 1.6.0 (ruby 1.8.7 patchlevel 330) (2011-03-15 f3b6154) (OpenJDK 64-Bit Server VM 1.6.0_20) [linux-amd64-java]

$ ruby -e '["stdin", "stdout", "stderr"].each { |s| system "./isatty #{s}" }'
Yes
Yes
Yes

$ jruby -e '["stdin", "stdout", "stderr"].each { |s| system "./isatty #{s}" }'
No
No
No

I tried to patch Ruby on Rails to make rails dbconsole working with jdbcpostgresql adapter, but I noticed that started psql command has no prompt because psql detected not interactive environment using isatty function.
