Looks like no, the JRuby engine used by BSF 3.0-beta2 doesn't work with
JRuby 1.1.2 or 1.1.3 as there have been some non-compatible changes. We
need to upgrade BSF to the latest engine which works with JRuby 1.1.3 and
the earlier JRuby releases.
I am using JRuby 1.0.1 with BSF 3.0-beta2 and it works fine. Due to this
reported on JRuby  I want to upgrade my JRuby version. I tried this but
it failed with the following exception. Are there any plans to upgrade the
supported JRuby version?
