Hi,
  I have a situation where I want to compartmentalize each script I evaluate in an interpreter. Right now, I'm using a separate interpreter for each script. Is there a significant cost to doing this? The reason is that I set some variables on the interpreter that are unique to each script and I don't want any co-mingling of these variables or access.

  What is the basic overhead cost of an interpreter? e.g. threads.

Also, I have noticed a peculiar thing. In a callback method from my application to a 'class' instantiated in beanshell and exposed to the Java app, some variables will not access properly WITHOUT a class declaration. The script just halts when you try to access, without a runtime exception. I'm using the latest beta jar of BSH and JDK1.5_01.

Thank you!
