Problems reading Java Hashtables from Jruby 1.3.1

Ruby JRuby

Hello guys,

I am having a big problem and it looks like a bug in jruby.

I have two java hash tables: hash1 and hash2. Both hashes have the same
key
but different data. Both hashes are generated in Java classes executed
from
Ruby code. Then I need to read a process both hashes within the ruby
code,
so I do the following:

hash1.each { |key, data|
puts hash2
puts hash2[key]
}

All the first puts print the complete list of key/value pairs without
any
problems. The second line is NIL. Why?

Thanks in advance,

GA

It sounds like a bug to me too. If you could make a small reproduction
with
a simple Java class and a Ruby script and attach to a JIRA, that would
great!

Make sure also you’re seeing what you THINK you’re seeing. “puts” can be
deceiving.

ruby -e ‘a = {“6”, 10}; b = {6, 10}; puts a; puts b; p a; p b’
610
610
{“6”=>10}
{6=>10}
