Ian Connor commented on JEXL-145:
---------------------------------

A potential fix is to replace code of the format
{{
String actual = sandbox.execute(obj.getClass().getName(), method);
}}
with
{{
String objClassName = (obj instanceof Class) ? ((Class<?>)obj).getName() : 
obj.getClass().getName();
String actual = sandbox.execute(objClassName, method);
}}

> Incorrect test case in SandboxTest

>             Project: Commons JEXL
>          Issue Type: Bug
>    Affects Versions: 2.1.1
>         Environment: JDK 1.7.0_45
>            Reporter: Ian Connor
>
> Whilst debugging blacklisting of static functions using the Sandbox class and 
> unable to get it to work I checked the testcase SandboxTest. I subsequently 
> found that the test of System.exit() in testRestrict() passes not because 
> System.currentTimeMillis() is whitelisted but because of a signature mismatch 
> i.e System.exit() requires an int parameter. Changing the expression to 
> System.exit(1) causes the test to end prematruely due to exit() being called.
> The white listing fails in SandboxUberspectImpl.getMethod() because obj is a 
> Class and getClass().getName() returns "java.lang.Class" which doesn't match 
> "java.lang.System" as specified in SandboxTest.testRestrict().
