https://s3.amazonaws.com/jruby.org/downloads/9.2.5.0/jruby_windows_x64_9_2_5_0.exe

[kares]

interesting. what is your rubygems version? jruby -S gem -v

seems that this is an incompatibility with MRI (at least since 2.3) :

2.3.6 :001 > RbConfig::TOPDIR
 => "/opt/local/rvm/rubies/ruby-2.3.6" 

... should be an easy fix but if RGs depends on this JRuby needs to figure out how to set for embed mode

[anup1710]

rubygems version is

$ jruby -S gem -v
2.4.8

[kares]

just for the record TOPDIR was added, however I am still not sure how you run into this.
9.2.5.0 comes with RGs 2.7.x installed, and also the lines from the trace do not much with 2.4.8
also there seems to be no TOPDIR usage in 2.4.8 or shipped 2.7 version

Thanks for the quick response and fixing the issue. I will check the changes and let you know. I am also not sure why its coming, I have only installed jruby from .exe file and tried to install the bundler to upgrade my project.
