Subject [jira] Commented: (AMQ-1088) TransactionContext class cast exception

Kevan Miller commented on AMQ-1088:
-----------------------------------

I've seen this problem on 4.1.0. Don't care for the above patch, as it can result in an NPE
on 4.1.0 (if length is 0, return a zero length array, not null), but certainly agree with
the sentiment...

I'm not sure where the type information is being lost. The data type in the broker is XATransactionId[].
But the type in client is DataStructure[]. In my case, the length of the array is zero --
not sure if that's significant...

Here's my stack trace:

>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Connector
>    Affects Versions: 4.0.1
>         Environment: XP - jre 1.4
>            Reporter: Mary Nicholas
>            Priority: Minor
>
> The class org.apache.activemq.TransactionContext throws a class cast exception on the
recover(int flag) method on the line (or at least it does with jdk1.4) return (XATransactionId[])
receipt.getData();
>  
> It cannot cast the list of DataStructure[] to XATransactionId[]. I just unpacked it locally
as a fix (as seen below) and it worked fine. Have not checked it in though in case others
with more experience on this one disagree.
> DataStructure[] x = receipt.getData(); 
>  
> if (x.length > 0)
> {
>       XATransactionId xaId[] = new XATransactionId[x.length];
>       int count = 0;
>       for (count =0; count < x.length; count++)
>                     xaId[count] = (XATransactionId)x[count]; 
>                     
>       return xaId;
