Description

The error occurs during the bootstrap phase of an application I have been developing. In JRuby 1.6.7, there are no errors and the application is able to launch successfully. No changes to the code have been made between tests.

Some minor digging found that the NameError is raised when JRuby attempts to evaluate the line "require 'jruby'", called at the top of the initial script.

The included attachment uses the same command line information to execute as the JRuby 1.6.7 test, and contains verbose output.

The full command is:
jruby.bat -v -Ilib/ -J-Djruby.thread.pooling=true --fast --server --1.9 lib/gryphon.rb

Does removing any of your extra flags affect whether you get the exception?

Removing all JRuby specific commands and using

jruby.bat -v -Ilib/ lib/gryphon.rb

allows the application to successfully launch, however it appears there are still some warnings about require calls and a ClassNotFoundException being thrown for org.objectweb.asm.ClassReader .

Adding the new output as output3.log

ClassNotFoundException persists after JRuby-specific flags are removed.

Is org.objectweb.asm.ClassReader found in your jruby.jar?

$ jar tvf lib/jruby.jar | grep ClassReader

Versions 1.6.7 and 1.7.0-dev of JRuby's jruby.jar files do not seem to include that path or any reference to a ClassReader class.

Where did you get JRuby? I just checked snapshots from http://ci.jruby.org, as well as the released 1.6.7, and they all have it.

1.6.7 is from the JRuby.org website, I believe using the 64bit executable.

1.7 was from http://ci.jruby.org/snapshots/master/

We'll call this "Cannot Reproduce". It's likely it was something glitchy in the dev builds during this period.
