RuntimeError when calling to_s with jruby

[pinpox]

Hello
using Jruby with some html tags (Nokogiri xml elements) I get this error which crashes the program
the error doesnt always occur, so it is hard to provide a sample code, but it looks like

doc.css('meta').each do |t|
  puts t
  a << t.to_s
end

I think it might have to do with invalid encodings, but it's just a guess.
Is there a woraround for this?

Hi,

Thanks for reporting this.

Unfortunately, without more information we cannot reproduce and thus won't be able to help. Can you please provide whatever you can to help us reproduce? The XML document in question would be a great help, as would any ruby code running on the script that might crash.

We would additionally need information about your system, which you can get by running nokogiri -v and pasting the output here.

Hi @binaryplease, is this issue reproducible on windows only ? I googled for this error and it looks like JRuby encoding issue that only on windows platforms.

[flavorjones]

Closing, pending more information from the original poster.

Hi have a similiar problem, that can be reproduced whit this snippet:

require 'nokogiri'
html_fragment=<<-eos
  <img width="16" height="16"  src="/icons/graycol.gif" border="0" alt="Inactive hide details for &quot;User&quot; ---19/05/2015 12:55:29---Provvediamo subito nell&#8217;integrare">
eos
doc = Nokogiri::HTML(html_fragment,nil,"ISO-8859-1")
doc.to_html

using

i obtain this error:

I looked at this issue briefly. Looks like the RuntimeException root cause is UnmappableCharacterException being thrown on this line. Looks like for some reason we're getting back invalid characters. note I verified this behavior on both jdk 7 and 8. The following patch ignores the invalid characters, but I'm still not sure why we're suddenly getting back invalid characters. Finally, the failure in SAX::TestParser is caused by xerces passing the string ?????... to the characters method of the parser handler. This could be caused by the same issue, i.e. we're passing invalid characters to xerces and xerces is replacing the invalid characters with question marks ?.

I'd like to run those tests outside the docker image, but unfortunately i'm having trouble getting jruby 9.1 to install on the host machine. i'll report back once i get it installed and run the test suite

[flavorjones]

@kares has submitted a fix for this in #1597

[flavorjones]

Fixed in master, will be in v1.7.1.
