Hello,
i whould like use xalanj2 (2.4.1) java library to compile some file xsl to 
translet file, but when I can try to build the translet file I receive this 
error:

Exception: java.io.NotSerializableException: 
org.apache.xalan.extensions.ExtensionNamespacesManager
java.io.NotSerializableException: 
org.apache.xalan.extensions.ExtensionNamespacesManager
	at java.io.ObjectOutputStream.outputObject(ObjectOutputStream.java:1148)
	at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:366)
	at java.io.ObjectOutputStream.outputClassFields

	at test.Compile.dumpTemplate(Compile.java:83)
	at test.Compile.run(Compile.java:55)
	at test.Compile.main(Compile.java:28)

and so, I  resolve the problem with  change this two class

ExtensionNamespaceManager and ExtensionNamespaceSupport 

To support Serializable interface and I recompile xalan

My question is this:

Is this the correct operation ?

also I looking for a path to xalan for this bug but I don�t find nothing

can someone help me ? 

thanks 

n.b. I�m sorry for my little English
