Thanks for the new release!
But: I tested this with the EclipseShell JRuby support (ie. simply
replaced it's JRuby jar with 0.8.3 from 0.8.2),
and now I keep on getting Exceptions when I evaluate some expressions.
Evaluating "1+1" and assignments seem to work, but anything else causes
various exceptions.
Eg. evaluating
require 'java'
causes:
java.lang.NullPointerException

Evaluating
def foo
"Foo"
end
causes:

I tried debugging this, but I couldn't really figure out what's up; one
place where an NPE happened was in the
EvaluateVisitor, line 1028 (last line of method public void
execute(EvaluationState state, InstructionContext ctx) );
Now... this worked before, so I'm wondering if you changed something in
the way a org.jruby.Ruby instance must be used.
Basically, what I do:
ruby_ = Ruby.getDefaultInstance();
Then reuse this ruby_ field to evaluate Scripts:
obj = ruby_.evalScript(code);
Do I have to set something else up?
Notes:
- I run these evalScript calls from different threads each time, is
that a problem?
- I use Java 5
Thanks,
