Dmitri Blinov updated JEXL-257:
-------------------------------
Description:
With regard to JEXL-256 I have noticed that a function which once had throw
IllegalArgumentException may be called immediately once again in script. The
problem is not always reproducible so I think it is somehow related to caching
and {{tryInvoke()}} being called first and {{invoke()}} called afterwards.
I can't produce test case at the moment but try to describe on the example. I
ommited some irrelevant details for the sake of simplicity...
First I have a function that evaluates Jexl script within script.
{code:java}
eval("java = 1")
{code}
Then I have a {{Context.set()}} that works like this
{code:java}
public void set(String name) {
if (name.equals("java"))
throw new IllegalArgumentException("java");
...
{code}
As I stated in JEXL-256, when {{Context.set()}} throws IllegalArgumentException
then script execution immediately terminates with this exception, and not with
JexlException. So, the function {{eval()}} im my case terminates with
IllegalArgumentException also.
Then I have two stack traces in the log, one for the first invocation
