I am getting the following incompatibility between Fixnum and Bignum on jruby
on linux.
jruby-1.5.3 > rand(2**64)
=> 8609428970434218151
jruby-1.5.3 > Integer("8609428970434218151").class
=> Bignum
jruby-1.5.3 > 8609428970434218151.class
=> Fixnum
jruby-1.5.3 > Integer("8609428970434218151") == 8609428970434218151
=> true
jruby-1.5.3 >
{Integer("8609428970434218151")=>'ook?'}.has_key?(8609428970434218151)
=> false
jruby-1.5.3 >
{8609428970434218151=>'eek?'}.has_key?(Integer("8609428970434218151"))
=> false
This looks like a bug to me but I could have missed something.
