Hi,
I’m trying to install RCov without the native extension with JRuby
1.1.2. And I’m getting an exception.
the steps I’m following are:
get the rcov-0.8.1.2 tarball -
http://rubyforge.org/frs/download.php/28270/rcov-0.8.1.2.tar.gz
install rcov by : jruby setup.rb all --without-ext
and boom I get the following exception.
My question is as follows… a) can anyone shed a little light on how I
should go about debugging this issue? I need to determine if the error
is a JRuby bug or something else. How do people generally debug from
ruby into java? If this is a bug in Jruby I’d like to try and find out
for sure before I go and submit a bug. Thanks for any advice.
Exception:
Exception in thread “main” java.lang.NullPointerException
