jruby-user - issue with paths starting with to ruby programs run by jruby.exe and jruby.bat

My apologies if this is known and/or not an "issue". (I had a quick look
through maybe possible issue categories in the codehaus Issues Navigator,
including all the Windows issues, but I couldn't see anything similar to
this.)
I've just installed JRuby 1.5.1 using the Microsoft Windows installer
jruby-windows-1-5-1.exe.
Using a small sample ruby program C:rubyvp.rb (but the issue seems to be
with any ruby program):
puts "* ver=#{RUBY-VERSION}; plat=#{RUBY-PLATFORM};"
If I start the path to a ruby program with a or a /, then JRuby seems to
append that path to the current working directory. (Which doesn't happen if
the path to the ruby program starts with C:, .., ...., etc.) Is this
intentional, or might it be a bug?
I've got other examples of this behaviour, and I'd be happy to post these,
but the following example seems to show all the significant aspects of this
behaviour, and seems to behave consistently with what I've just set out.
If if might be an as yet unreported bug, then I'll be happy to try to submit
a bug report.

P.S.
I've just deleted JRuby 1.4 from my system (because 1.5.1 seemed to be
working fully), otherwise I'd have also tried it with that.
