Jochen Wiedmann commented on XMLRPC-127:
----------------------------------------
When running your example, I receive the following error code:
Failed to invoke method setMap in class xmlrpctest.TestRPCImpl:
java.lang.String cannot be cast to java.lang.Integer
I find this quite understandable, because map keys can only be string, at least
according to the XML-RPC spec. In other words, parameters like Map<Integer,...>
cannot work.
> Serialization/deserialization of Map does not retain correct datatype

> Key: XMLRPC-127
> URL: http://issues.apache.org/jira/browse/XMLRPC-127
> Project: XML-RPC
> Issue Type: Bug
> Components: Source
> Affects Versions: 3.1
> Reporter: Jimisola Laursen
> Priority: Critical
> Attachments: test.zip
>
>
> Believe that this is quite severe bug unless I did something very wrong.
> When sending/rretrieving a Map over XMLRPC the datatype is not correct. I've
> only checked for the keys, but the error might exist for the values as well.
> Provided is a simple unit test to illustrate the bug. To reproduce run the
> unit tests in SerializationTest.
> It has two test methods:
>
> 1) one that calls a static method and
> 2) and another that calls a method over XMLRPC which in turns call the same
> static method
> The latter fails with a ClassCastException. Instead of the key being the
> expected Integer it is a String.
> >From Console:
> [...]
> key: 21
> value: twentyone
> 21 -> 'twentyone'
> key: 1
> value: one
> 1 -> 'one'
> [...]
> key: 21
> >From Debug -> Variables (in Eclipse):
> entry HashMap$Entry<K,V> (id=13)
> key "21"
> count 2
> hash 1599
> offset 0
> value char[2] (id=27)
> value "twentyone"
> count 9
> hash 0
> offset 0
> value char[9] (id=29)
> As you can see 21 is a char[2] and not an integer as expected.
