[jruby-dev] [jira] (JRUBY-7047) java.lang.NoClassDefFoundError: json/ext/ByteListTranscoder

[Jordan Sissel (JIRA)]

Jordan Sissel created JRUBY-7047 java.lang.NoClassDefFoundError: json/ext/ByteListTranscoder Issue Type: Bug Affects Versions: JRuby 1.7.1, JRuby 1.7.0 Assignee: Thomas E Enebo Created: 28/Dec/12 4:53 PM Description: % ruby -rjson -e 'JSON.parse("{}")' ClassLoader.java:-2:in `defineClass1': java.lang.NoClassDefFoundError: json/ext/ByteListTranscoder ... The error above is a new problem to me. I've been using JRuby 1.7.0 for a long time and have only seen this just now. This occurs regardless of whether or not the 'json' gem is installed (jruby w/ ruby 1.9 comes with json, anyway, right?) Stracing the process, I see it successfully find the json's parser.jar which indeed includes json/ext/ByteListEncoder.class. I don't know why it cannot find the class. Example: % jar tf /home/jls/.rvm/gems/jruby-1.7.1/gems/json-1.7.5-java/lib/json/ext/parser.jar | grep Byte json/ext/ByteListTranscoder.class This failure occurs in 1.7.0 and 1.7.1 for me, and only on this one machine. I have no idea what the problem is. I have done 'rvm reinstall 1.7.1' to try and reinstall a fresh jruby 1.7.1, but it does not fix it. Environment: fedora 17 rvm 1.17.2 java version "1.7.0_09-icedtea" OpenJDK Runtime Environment (fedora-2.3.3.fc17.1-x86_64) OpenJDK 64-Bit Server VM (build 23.2-b09, mixed mode) Project: JRuby Priority: Major Reporter: Jordan Sissel
