This question should have been posted in the Designer BIRT Reports section, and I'll move after I have replied.
 
 
So you'll want to use a Scripted Data Source / Scripted Data Set.
 
In the open event of the Scripted Data Set, you'll want to initialize your variable for the hashmap iterator (entriesIterator).
<pre class="_prettyXprint _lang-">
var myHashmap = new Packages.java.util.HashMap();

myHashmap.put("key1", "Value1");
myHashmap.put("key2", "Value2");
myHashmap.put("key3", "Value3");
myHashmap.put("key4", "Value4");
myHashmap.put("key5", "Value5");

//myHashmap.entrySet()
//[key1=Value1, key2=Value2, key5=Value5, key3=Value3, key4=Value4]

entriesIterator = myHashmap.entrySet().iterator();
</pre>
Then, in the fetch event, you'll want to loop through the entries and get its key and value.
<pre class="_prettyXprint _lang-">
if (entriesIterator.hasNext()) {
var e = entriesIterator.next()
row["key"] = e.getKey();
row["value"] = e.getValue();
return true;
}
else {
return false;
}
</pre>
Attached is the sample report design (was created in OS BIRT 4.6.0).
