Dennis Sosnoski resolved JIBX-213.
----------------------------------
Assignee: Dennis Sosnoski
Resolution: Fixed
Fix Version/s: JiBX 1.1.6
Fixed a couple of places where this type of error could occur when using longs
or doubles.
> Incorrect binding code generated for long data type (Won't DUP type on stack
> top 'long' because it must occupy exactly one slot, not '2'.)

> Key: JIBX-213
> URL: http://jira.codehaus.org/browse/JIBX-213
> Project: JiBX
> Issue Type: Bug
> Components: Generator Tools
> Affects Versions: JiBX 1.1.5
> Environment: Windows XP Pro SP2, CPU x86 Family 15 Model 4 Stepping 1
> GenuineIntel ~3200 Mhz, RAM 2GB
> Java(TM) SE Runtime Environment (build 1.6.0_04-b12)
> Reporter: Serguei Ouklonski
> Assignee: Dennis Sosnoski
> Fix For: JiBX 1.1.6
>
> Attachments: testcases.zip
>
>
> For simple input-only binding incorrect code is generated when "long" data
> type is present. Identical code with "int" instead of "long" is processed
> correctly.
> Attached is an archive containing two test cases:
> testcases
> bad-with-long
> bind
> good-with-int
> bind
> "bind" is a top-level java package. InTest2 is a main class, InTest2.xml is
> input file.
