Hi,

I have an application which - since some weeks (it became obvious after some weeks of JRuby 9k usage) and only from time to time (aka not easy reproducible) - is raising an java.lang.NoClassDefFoundError exception such as the following.

The class loading code did not change since a long time and the error happens not always.

The application itself is a combination of some rake tasks which may invoke Java code.

The odd situation is that the classes which cause the NoClassDefFoundError are never called directly by the JRuby code but indirectly through Java code which is called by JRuby. It's also not nessecarily the same missing class. It may also be a completely different jar where the missing class comes from. The jar loading code is

      $CLASSPATH << directory
      classLoader = JRuby.runtime.jruby_class_loader
      Dir.glob('%s/*.jar' % [directory]).each do |jar|
        @@semaphore.synchronize do
          # The well known require or CLASSPATH statements cause issues on
          # Windows in case the loaded and executed java code itself tries to
          # load jar files.
          #
          # Due to this we use
          # http://calavera.github.io/2011/02/09/jruby-class-loader-by-example.html
          classLoader.add_url(Java::JavaIo::File.new(jar).to_url)
        end
      end

I am seeking for guidenance what to look for. What has changed here, may it be related to the threading rake performs or are there changes with the JRuby class loader since 1.7? I definitely can confirm that the jar files are loaded at least once.

The used JRuby version is 9.0.1.0 and 9.0.4.0. The JVM is Oracle Java 1.8.0u60 using Windows 2008 R2 Server or Windows 2012 Server.

This is several years old and I suspect it was an environment issue or something we or the JDK have fixed. If you can still reproduce this on a recent JDK 8+ and JRuby 9.2+, please open as a new issue.
