JRuby 10.1 `circular causes` failures within nested rescue (e.g rspec's tests)

[chadlwilson]

There are failures within the rspec test suite that might expose some intentional or unintentional differences between JRuby 10.1 and CRuby 4.0.

https://github.com/chadlwilson/rspec/actions/runs/24822251102

Environment Information

jruby 10.1.0.0 (4.0.0) 2026-04-20 32f988b78c OpenJDK 64-Bit Server VM 21.0.10+7-LTS on 21.0.10+7-LTS +indy +jit [x86_64-linux]

Expected Behavior

• Tests should be passing; or any known differences understood so we can mark the tests as Pending or similar, and linked to upstream issues here.

Actual Behavior

circular causes

• rspec-support RSpec::Support.method_handle_for(object, method_name) fails with NameError when an undefined method is fetched from an object that has overridden method to raise an Exception

  stack

    1) RSpec::Support.method_handle_for(object, method_name) fails with `NameError` when an undefined method is fetched from an object that has overridden `method` to raise an Exception

I think it's possibly one problem; here's the simplest reproducer from rspec code I could get it down to:

# Used internally to get a method handle for a particular object
# and method name.
#
# Includes handling for a few special cases:
#
#   - Objects that redefine #method (e.g. an HTTPRequest struct)
#   - BasicObject subclasses that mixin a Kernel dup (e.g. SimpleDelegator)
#   - Objects that undefine method and delegate everything to another
#     object (e.g. Mongoid association objects)
def method_handle_for(object, method_name)
  ::Kernel.instance_method(:method).bind(object).call(method_name)
rescue NameError => original
  begin
    handle = object.method(method_name)
    raise original unless handle.is_a? Method
    handle
  rescue => e
    raise original
  end
end

class RedefinesMethod
  def method
    raise Exception.new
  end
end

### REPRODUCER-ONLY CODE
puts "Testing #{RUBY_VERSION} / #{defined?(JRUBY_VERSION) ? JRUBY_VERSION : 'CRuby'}"
begin
  method_handle_for(RedefinesMethod.new, :some_undefined_method)
rescue NameError => e
  raise "NameError message not as expected: #{e.message}" unless e.message =~ /undefined method ['`]some_undefined_method' for class ['`]RedefinesMethod'/
  puts "OK!"
rescue
  puts "FAIL!"
  raise
end

Possibly some issue/missing case in ed58f10 ?

I think the following is the same effect as your example:

begin
  foo
rescue NameError => ne
  begin
    method
  rescue => e
    raise ne
  end
end

The original NameError here is captured and then during its rescue block another ArgumentError gets raised with the NameError as its cause. When we proceed later to re-raise the NameError, we try to set the cause fo the ArgumentError and boom.

I believe the ArgumentError cause is correct but perhaps we should not be trying to re-set a cause for a previously-raised exception (the NameError).

[headius]

Here's the output of running my reduced script on 10.1:

 $ jruby blah2.rb
ArgumentError: circular causes
  <main> at blah2.rb:7
ArgumentError: wrong number of arguments (given 0, expected 1)
  <main> at blah2.rb:5
NameError: undefined local variable or method 'foo' for main
  <main> at blah2.rb:2

Note that 10.0 does the same thing but does not have the additional checks to error for the circular cause:

$ cx jruby-10.0 jruby blah2.rb
NameError: undefined local variable or method 'foo' for main
  <main> at blah2.rb:2
ArgumentError: wrong number of arguments (given 0, expected 1)
  <main> at blah2.rb:5
NameError: undefined local variable or method 'foo' for main
  <main> at blah2.rb:2

If instead of an ArgumentError we trigger another NameError, the bug is not seen because it appears that we do not set the new NameError's cause to the original NameError:

begin
  foo
rescue NameError => ne
  begin
    bar
  rescue => e
    raise ne
  end
end

Output on JRuby 10.1:

$ jruby blah2.rb
NameError: undefined local variable or method 'foo' for main
  <main> at blah2.rb:2
NameError: undefined local variable or method 'bar' for main
  <main> at blah2.rb:5

[headius]

There are two failing raise specs I missed during implementation because they were tagged by @andrykonchin during a spec update:

ee1e5b4#diff-e33351e056347af04ee7e3cb8a98417b675a46b558d8284f7ecb6aa0e2baff97R9-R10

We probably need a better system for adding or auditing these tags because lots of functionality is being forgotten in the process. During 10.1 I primarily focused on new failures and did not notice these specs were tagged off.

[chadlwilson]

Interestingly, your reduced script has slightly different stacks CRuby vs JRuby across all versions:

$ for v in 3.1 3.4 4.0 jruby-9.4 jruby-10.0 jruby-10.1; do mise x ruby@$v -- ruby reprod.rb; done

Testing 3.1.7 / CRuby
reprod.rb:41:in `<main>': undefined local variable or method `foo' for main:Object (NameError)

  foo
  ^^^

Testing 3.4.8 / CRuby
reprod.rb:41:in '<main>': undefined local variable or method 'foo' for main (NameError)

  foo
  ^^^

Testing 4.0.2 / CRuby
reprod.rb:41:in '<main>': undefined local variable or method 'foo' for main (NameError)

  foo
  ^^^

Testing 3.1.7 / 9.4.14.0
NameError: undefined local variable or method `foo' for main:Object
  <main> at reprod.rb:41
ArgumentError: `method': wrong number of arguments (given 0, expected 1)
  <main> at reprod.rb:44
NameError: undefined local variable or method `foo' for main:Object
  <main> at reprod.rb:41


Testing 3.4.5 / 10.0.5.0
NameError: undefined local variable or method 'foo' for main
  <main> at reprod.rb:41
ArgumentError: wrong number of arguments (given 0, expected 1)
  <main> at reprod.rb:44
NameError: undefined local variable or method 'foo' for main
  <main> at reprod.rb:41


Testing 4.0.0 / 10.1.0.0
ArgumentError: circular causes
  <main> at reprod.rb:46
ArgumentError: wrong number of arguments (given 0, expected 1)
  <main> at reprod.rb:44
NameError: undefined local variable or method 'foo' for main
  <main> at reprod.rb:41

In that the ArgumentError to method is completely elided on CRuby; which is kind of what I'd expect since it has been rescued and thrown away. Perhaps that's related to why JRuby has a "circular cause" risk here where CRuby does not?

Similarly if raising another NameError - on CRuby there is no reference to bar; it was rescued and discarded:

$ for v in 3.1 3.4 4.0 jruby-9.4 jruby-10.0 jruby-10.1; do mise x ruby@$v -- ruby reprod.rb; done

Testing 3.1.7 / CRuby

edit: The StackOverflow is unrelated; will track on rspec at rspec/rspec#321

[headius]

I've done the big refactor of Kernel#raise in #9407. It fixes my reduced case but it does not yet fix your longer example. Should be easier to figure out the missing logic now, though.

[headius]

This is fixed by #9407 but I'm only partially sure of that fix. Ultimately the trigger was that NameError did not get a nil cause set early enough, so when the nested situation happens in your example it tries to implicitly gain a cause that turns out to be circular. Along the way fixing other cause behaviors, I also started setting the cause for NameError and ArgumentError which "fixed" this.

[headius]

Fixed by #9407.
