redcar 0.13 fails - Windows 7, Ruby 2, Java 7 64bit u45

[aplatypus]

Hi.

I have listed the command line transcript below. After installing redcar, the program fails because the JVM installed is a 64-bit Java and Jruby.

Also, the install instructions are a little ambiguous. In any case, I installed the gem with Jruby as well but this also fails, albeit at least the Java 64-bit worked OK (apparently).

The common complaint concerns the use of Config instead of RbConfig, see below.
