[jruby-dev] [jira] (JRUBY-6812) 1.7 regression handling Java exceptions

[Karol Bucek (JIRA)]

Karol Bucek created JRUBY-6812 1.7 regression handling Java exceptions Issue Type: Bug Affects Versions: JRuby 1.7.0.pre1 Assignee: Unassigned Components: Java Integration Created: 03/Aug/12 6:57 AM Description: I'm really sorry as this is going to be pretty vague, I tried to narrow things down but have been only able to spot the failure while running with RSpec (2.11 version seems to not matter that much as far as I tried). seems as a regression to me as things work well with jruby 1.6.7 (1.8 and 1.9 as well) but not with jruby-head, here's a piece of code : require 'rhino' begin raise Rhino::Ruby::Exception.new(42) rescue java.lang.Exception => e puts "rescued exception class name: #{e.class.name}" puts "is is a Rhino::Ruby::Exception ? #{e.is_a?(Rhino::Ruby::Exception)}" end now pasting this into an irb seems to work, but not when in a spec : git clone git://github.com/cowboyd/therubyrhino.git bundle install bundle exec rspec spec/rhino/ruby_spec.rb -e Exception should end up with a failure : 1) Rhino::Ruby::Exception outcomes as ruby errors in function calls Failure/Error: e.should be_a(Rhino::Ruby::Exception) expected org.jruby.proxy.org.mozilla._javascript_._javascript_Exception$Proxy2: [object Fixnum] to be a kind of Rhino::Ruby::Exception # ./spec/rhino/ruby_spec.rb:413:in `(root)' spec is a little more complicated but replacing the highlighted line with the above code fails as well (note again it passes all fine with 1.6.7) : begin raise Rhino::Ruby::Exception.new(42) rescue java.lang.Exception => e e.should be_a(Rhino::Ruby::Exception) # ... Environment: jruby 1.7.0.preview2.dev (ruby-1.9.3-p203) (2012-08-01 5fe8b45) (Java HotSpot(TM) Server VM 1.6.0_32) [linux-i386-java] Project: JRuby Priority: Major Reporter: Karol Bucek
