JRuby 1.6.0-RC1のバグの切りわけができない
久々にブログを書いてみました。 Nendoのテストスイートを走らせているのだが、JRuby 1.6.0-RC1のバグっぽい挙動に悩されている。 なぜか、次のように失敗する。( CRuby 1.9.2-p136では正常にパスする ) expectedとgotの文字列を見ても同じように見えるのだが。
現象
ruby -I ./lib /usr/local/bin/rspec -b ./test/nendo_spec.rb
.........F.F..................FFFFFFFFFFFFFFFFFFFFFFF
Failures:
1) Nendo when call evalStr() with literals should
Failure/Error: @nendo.evalStr( ' "日本語" ' ).should eql( '"日本語"' )
expected "\"\xE6\x97\xA5\xE6\x9C\xAC\xE8\xAA\x9E\""
got "\"\xE6\x97\xA5\xE6\x9C\xAC\xE8\xAA\x9E\""
(compared using eql?)

UTF-8の文字列の扱いがうまくいかないのかな？ Nendoの処理系は instance_eval() を使っているので、次のようなspecファイルでも失敗すると予想したが、失敗しない。 t_spec.rb
#!/usr/bin/env ruby
# -*- encoding: utf-8 -*-
#
describe Kernel, "when call evalStr() with literals" do
it "should" do
instance_eval( ' "\"abc\"" ' ).should == '"abc"'
instance_eval( ' "\"日本語\"" ' ).should eql '"日本語"'
end
end
実行結果
$ rspec t_spec.rb
.

そんなわけで、バグ報告したいけど問題を絞り込めないのでちょっと保留かなー。 CRubyでは動くので、JRuby側に問題があると思うだけどなー。
