Crashing when populating a list using the new ios vm, working when setting ios.newVM=false

[GoogleCodeExporter]

What steps will reproduce the problem?
Not sure how you can reproduce it but it crashes somewhere at this line of code:

reports.addComponent(createGroup(key, map.get(key)));

which is in this routine (class attached):
public void init() {
         Log.p("reports init");         

         reports.removeAll();

         Map<String, List<ReportInfo>> map = new HashMap<String, List<ReportInfo>>();

         for (ReportInfo ri : model.getReportRuns()) {
            if (!map.containsKey(ri.getGroupName()))
               map.put(ri.getGroupName(), new LinkedList<ReportInfo>());

            map.get(ri.getGroupName()).add(ri);            
         }       

         for (String key : new TreeSet<String>(map.keySet())) {            
             reports.addComponent(createGroup(key, map.get(key)));         
         }      

      }

What is the expected output? What do you see instead?
Expected output attached. Crashing without any error using the new vm.

We can't reproduce this.
You will need to extract a test case we can actually run in order to submit an 
issue.

I can confirm that using TreeSet will cause the crash. The app is working after 
I remove TreeSet.

Are you still getting this issue?
If so I will need a test case so I can reproduce it.

The issue occurs when TreeSet is used to have a sorted list.

for (String key : new TreeSet<String>(map.keySet())) {            
             reports.addComponent(createGroup(key, map.get(key)));         
         }

That is not a test case. 
A test case is an app I can actually run e.g. 
https://code.google.com/p/codenameone/issues/detail?id=1304 see the initial 
attachment of TWMain. I could run it and reproduce the issue which helped a 
great deal in tracking the problem.

Here it is.

That is way too much code, finding a VM bug is difficult with such a big test 
case since VM bugs are inherently deep inside. Please try to remove all 
redundant code, we could do this ourselves but its much harder for us since we 
aren't familiar with your code.

I already specified where the issue was. If I do not use TreeSet it will
work.
Most of the code is just to dummy up the data which is the same data that I
use for testing.
The issue is not critical, I just won't use TreeSet to make it work.

Anyway, have removed some code.

That's not code I can compile and run. There are many imports in it that point 
to your classes/libraries.

codename1 or java libraries.
