Jsr223 legacy behaviour


hi all,

I have to write a jsr223 jruby script for the attribute resolver of

I’m a bit lost to get right the Context Instance Type switches from

My problem is:
container inject variables as constants, and different concurrent
invocations of a script overwrite each other data.

Well, I believe it’s something related with the Context Instance Type,
but maybe I’m wrong.

What I can say for sure is that the jruby scripts work fine with
jruby-1.0.0.jar and a legacy jruby-engine-20080611.jar.

Which configurations let a modern jruby.jar to work in emulation of the
jsr223 behaviour of jruby-engine-20080611?

thank you,



Hi Francesco,

Context Type: SingleThread
Variable Behavior: Global Local

should work the same as jsr223 reference implementation,

Defaults are Singleton and Transient, so you need to explicitly specify
values. But, global local variable behavior is set when JSR223 engine is
instantiated as far as I know.

Hope this helps,

Are these the correct settings according to your kind response?

jetty 28117 9.7 40.5 2776288 835200 ? Sl 08:18 1:28
/usr/bin/java -Xmx1024m -XX:MaxPermSize=128m
-Didp.home=/opt/shibboleth-idp -Djetty.home=/opt/jetty
-Djetty.base=/opt/jetty-base -Djava.io.tmpdir=/opt/jetty-base/temp -jar
/opt/jetty/start.jar jetty-started.xml

If yes, unfortunately, it does not fix my issue:
globals carry on getting overwritten.

Thank you,
