RubyMine JRuby-1.7.0 Breakpoint from Unit Test or Script

My environment:

JRuby-1.7.0

Rails 3.0.0

RubyMine 2016.1.2

I can set a breakpoint successfully when launching the full webapp using rails s:

/home/user/.rvm/rubies/jruby-1.7.0/bin/jruby --1.9 -X+O -J-Djruby.compile.mode=OFF -J-Djruby.debug.fullTrace=true -e at_exit{sleep(1)};$stdout.sync=true;$stderr.sync=true;load($0=ARGV.shift)        /home/user/.rvm/gems/jruby-1.7.0/gems/ruby-debug-ide-0.6.1.beta2/bin/rdebug-ide --disable-int-handler --evaluation-timeout 10 --rubymine-protocol-extensions --port 55357 --host 0.0.0.0 --dispatcher-port 47578 -- /home/user/dev/share/app/script/rails server -b 0.0.0.0 -p 3000 -e development

but when I run a script or a simple test with:

/home/user/.rvm/rubies/jruby-1.7.0/bin/jruby --1.9 -X+O -J-Djruby.compile.mode=OFF -J-Djruby.debug.fullTrace=true -e at_exit{sleep(1)};$stdout.sync=true;$stderr.sync=true;load($0=ARGV.shift)        /home/user/.rvm/gems/jruby-1.7.0/gems/ruby-debug-ide-0.6.1.beta2/bin/rdebug-ide --disable-int-handler --evaluation-timeout 10 --rubymine-protocol-extensions --port 41191 --host 0.0.0.0 --dispatcher-port 48760 -- /home/user/dev/share/app/test/standalone/exercise_some_code.rb

or:

/home/user/.rvm/rubies/jruby-1.7.0/bin/jruby --1.9 -X+O -J-Djruby.compile.mode=OFF -J-Djruby.debug.fullTrace=true -e at_exit{sleep(1)};$stdout.sync=true;$stderr.sync=true;load($0=ARGV.shift) -Itest /home/user/.rvm/gems/jruby-1.7.0/gems/ruby-debug-ide-0.6.1.beta2/bin/rdebug-ide --disable-int-handler --evaluation-timeout 10 --rubymine-protocol-extensions --port 40324 --host 0.0.0.0 --dispatcher-port 39000 -- /home/user/dev/share/app/test/unit/some_test.rb --name=test_incident_date

The breakpoint is ignored. Any thoughts? I am out of ideas here.
