Key: JRUBY-5849
URL: http://jira.codehaus.org/browse/JRUBY-5849
Project: JRuby
Issue Type: Improvement
Environment: $ java -version
java version "1.6.0_22"
OpenJDK Runtime Environment (IcedTea6 1.10.1) (6b22-1.10.1-0ubuntu1)
OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)
Reporter: kristian meier
Assignee: Thomas E Enebo
Priority: Minor
ubuntu 11.04 comes with IcedTea6 which allows to choose between -client -cacao
and -jamvm runtime environment and I found jamvm gives a second better startup
which is a lot for these small commandline tools.
a little patch in the jruby executable would allow me to configure it for my
