FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
Every time the method getScriptContext is called, a new instance of SimpleScriptContext is created. This calls
        reader = new InputStreamReader(System.in);
        writer = new PrintWriter(System.out , true);
        errorWriter = new PrintWriter(System.err, true);
immediately to be replaced by
        ctxt.setReader(context.getReader());
        ctxt.setWriter(context.getWriter());
        ctxt.setErrorWriter(context.getErrorWriter());
The creation of the reader and writers causes significant overhead in the sense that these objects need to be immediately garbage collected again.
When this method is called a lot, a new Constructor for SimpleScriptContext that allows the passing of the reader and writers would be a lot more efficient.

This bug can be reproduced always.
