Nested exception is converted to message and can not be retrieved

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Throw a java exception in script.
2. Get the detailed exception as root cause from the wrapping exception
3.

What is the expected output? What do you see instead?
Expect to get the root cause exception. But the nested exception is converted 
to message, and lost.

Please use labels and text to provide additional information.
It's not using the java exception chain mechanism, which is a nice feature for 
servceability.

Example:

try {
    new Interpreter().eval("class A{A(){throw new RuntimeException(\"The root cause\");}} new A();");
} catch (Exception e) {
    e.printStackTrace();
}
