Henri Biestro resolved JEXL-154.
--------------------------------
Resolution: Cannot Reproduce
> JEXL method lookup incorrectly interprets object array param as varargs
> -----------------------------------------------------------------------
>
> Key: JEXL-154
> URL: https://issues.apache.org/jira/browse/JEXL-154
> Project: Commons JEXL
> Issue Type: Bug
> Affects Versions: 2.1.1
> Reporter: David Loone
> Assignee: Henri Biestro
> Priority: Minor
> Fix For: 3.0
>
>
> Say I have an object in my context with a method like:
> {code}
> public <T> List<T> asList(T[] array) {
> return Arrays.asList(array);
> }
> {code}
> When I call that from a JEXL expression with something like:
> {code}
> utils.asList(["foo", "bar"])
> {code}
> The JEXL method finder seems to treat the method like a varargs method, and
> puts the whole string array into the first element of the formal parameter,
> rather than mapping the string array onto the object array. That is, the
> method receives an array of length 1, with that first element being a string
> array of length 2.
> To illustrate further, the problem goes away if I change the method to look
> like:
> {code}
> public <T> List<T> asList(T[] array, String ... dummy) {
> return Arrays.asList(array);
> }
> {code}
> since this forces the T[] array to be interpreted correctly.
