can not re-reify sub-class of a Java sub-class #8141
Description
This is a bit of a stretch, usually not something that happens in production but still Ruby class removing is not that uncommon.
class SubList < java.util.ArrayList
def initialize(arg1, arg2)
puts "initialize #{self}"
super(arg1 + arg2)
end
end
class SubSubList < SubList
end
p SubSubList.new(1, 2)
Object.send(:remove_const, :SubSubList)
# ... while parent SubList stays around (if it's removed as well it's not an issue)
class SubSubList < SubList
end
p SubSubList.new(1, 2)Environment Information
Provide at least:
- JRuby 9.3.0.0 - 9.4.6.0
Expected Behavior
- Script works, reification is able to deal with the removed sub-class while parent was kept
Actual Behavior
- Second
SubSubList.newwill fail:
initialize
#<SubSubList: []>
ArgumentError: wrong number of arguments for constructor
