>             Project: Seam
>          Issue Type: Bug
>          Components: Remoting, Test Harness
>    Affects Versions: 2.2.0.GA
>         Environment: Java(TM) SE Runtime Environment (build pxi3260sr4-20090219_01(SR4))
> IBM J9 VM (build 2.4, J2RE 1.6.0 IBM J9 2.4 Linux x86-32 jvmxi3260-20090215_29883 (JIT enabled, AOT enabled)

>             Fix For: 2.2.1.CR1
> org.jboss.seam.test.unit.RemotingTest.testMapWrapper()
> The test expects the elements to be returned in the same order in which they were created:
> <map><element><k><str>bar</str></k><v><str>zzzzz</str></v></element><element><k><str>foo</str></k><v><str>aaaaa</str></v></element></map>
> However, on IBM JVM, the order of elements is not preserved in the returned tree, so the tree looks like this:
> <map><element><k><str>foo</str></k><v><str>aaaaa</str></v></element><element><k><str>bar</str></k><v><str>zzzzz</str></v></element></map>
> The assumption of the test is incorrect, because the marshal() method of MapWrapper class iterates over a Set of keys and thus the order cannot be guaranteed.
