Summary
The System.assertEquals(Map<ID,ID> , Map<ID,ID> ) fails for identical Map<ID,ID> in summer 13.

Repro
Steps to Replicate:

Create a test class and run test . It will fail with following error-

System.AssertException: Assertion Failed: Expected: {001D000000JVGTrIAP=001D000000JVGTrIAP}, Actual: {001D000000JVGTrIAP=001D000000JVGTrIAP}
Stack Trace Class.Summer13RegressionTests.mapIdComparisionTest: line 26, column 1

Apex class
============

@isTest class Summer13RegressionTests {

@isTest static void mapIdComparisionTest() {

final Map <Id, Id> identicalMapIdA = new Map<Id, Id>{'001D000000JVGTr' => '001D000000JVGTr'};
final Map <Id, Id> identicalMapIdB = new Map<Id, Id>{'001D000000JVGTr' => '001D000000JVGTr'};

final Map<String, String> identicalMapStringA = new Map<String, String>{};
final Map<String, String> identicalMapStringB = new Map<String, String>{};

for (Id keyId : identicalMapIdA.keySet()){
identicalMapStringA.put(keyId, identicalMapIdA.get(keyId));
}
for (Id keyId : identicalMapIdB.keySet()) {
identicalMapStringB.put(keyId, identicalMapIdB.get(keyId));
}

//comparing the keysets also works
System.assertEquals(identicalMapIdA.keyset(), identicalMapIdB.keyset());
//comparing the values also works
System.assertEquals(identicalMapIdA.get('001D000000JVGTr'), identicalMapIdB.get('001D000000JVGTr'));
// Workaround is to put Map<Id, Id> into Map<String, String>
System.assertEquals(identicalMapStringA, identicalMapStringB);

// Comparision of two identical Map<Id, Id> fails in Summer '13 (28.0), was passing in Spring '13 (27.0)
System.assertEquals(identicalMapIdA, identicalMapIdB);
// using system.assert also fails
System.assert(identicalMapIdA==identicalMapIdB);
}
}

Workaround
Convert Map<Id, Id> into Map<String, String>
