You can remove the serialize package and the following list of classes 
and still have Ecma-confirming implementation:

ClassNameHelper
ClassRepository
FunctionObject
ImporterTopLevel
Invoker
LazilyLoadedCtor
NativeJavaPackage
NativeJavaObject
NativeJavaMethod
JavaMembers
NativeJavaArray
Synchronizer

You will have to comment out some of the code after the removal of the 
whole list, but the interpreter should still work OK. You can also 
remove all deprecated code and run any code shrinker on the rest of classes.

The code size for 1.5R2 was increased compared with 1.5R1 as a result of 
internal reorganization but that decreased the total memory consumption 
by JVM significantly.
